Case Study: Salesforce to HubSpot Migration Guide

Migrating from Salesforce to HubSpot is one of the most common CRM transitions in the B2B world, yet it remains one of the most misunderstood. Companies assume it is simply a matter of exporting data from one platform and importing it into another. In reality, a successful CRM migration involves rethinking your sales processes, cleaning years of accumulated data debt, retraining your team, and rebuilding automations from scratch. Get it wrong and you lose pipeline visibility for weeks, frustrate your sales team, and risk damaging customer relationships.

This case study follows the journey of a mid-market B2B SaaS company with 85 employees and a 25-person sales team as they migrated from Salesforce Professional to HubSpot Sales Hub Enterprise. The project was completed in 90 days from kickoff to full adoption. We will cover the motivations behind the switch, the detailed timeline, the specific challenges encountered, the data migration strategy, and the measurable results after six months on HubSpot.

Whether you are actively planning a migration or simply evaluating whether HubSpot could be a better fit than your current Salesforce setup, this case study provides a realistic blueprint for what the process actually looks like.

Why the Company Decided to Leave Salesforce

The company had been using Salesforce Professional for four years. While Salesforce served them well during their initial growth phase, several pain points had compounded over time. The sales team found the interface unintuitive and relied heavily on the Salesforce admin for basic tasks like creating reports or modifying pipeline stages. Customization costs were escalating, with every workflow change requiring a consultant at $150 to $250 per hour. The annual licensing cost had grown to over $72,000, and the team was only using about 30 percent of available features.

The marketing team was using HubSpot Marketing Hub separately, creating a constant sync challenge between the two platforms. Lead handoff from marketing to sales was clunky, attribution data was unreliable, and the two teams operated with different definitions of key metrics. Unifying on a single platform was the primary motivation for the switch.

After a three-month evaluation period comparing HubSpot Sales Hub Enterprise, Pipedrive, and staying on Salesforce with additional integrations, the leadership team chose HubSpot for three reasons: native marketing-sales alignment, a more intuitive user interface, and a lower total cost of ownership over three years.

The 90-Day Migration Timeline

The migration was structured into three distinct phases, each lasting approximately one month. Here is how the timeline unfolded.

Phase 1: Audit and Planning (Days 1-30)

The first month was entirely focused on preparation. No data was moved during this phase. The team conducted a full audit of the existing Salesforce instance, documenting every custom object, field, automation rule, report, and integration. This audit revealed 47 custom fields on the contact object, 23 on the deal object, 12 active workflow rules, 8 integrations with external tools, and over 340,000 contact records.

The project team included a dedicated HubSpot migration specialist (contracted), the internal Salesforce admin, one sales operations manager, and the VP of Sales as executive sponsor. Weekly meetings were held to review progress and make decisions on data mapping.

Key decisions made during Phase 1 included which custom fields to migrate (only 31 of 47 were actually used), how to map Salesforce opportunity stages to HubSpot deal stages, which historical activities to bring over (emails and meetings from the last 24 months only), and how to handle duplicate records (5,200 duplicates were identified and merged before migration).

Phase 2: Data Migration and Configuration (Days 31-60)

The second month was when the heavy lifting happened. The team used a combination of HubSpot's native Salesforce import tool and a third-party migration service for complex object relationships.

The migration sequence was carefully ordered to preserve data integrity. First, companies were migrated. Then contacts were mapped to their parent companies. Then deals were migrated with their associated contacts and companies. Then activities (emails, calls, meetings, notes) were attached to their parent records. Finally, custom properties and lifecycle stages were mapped.

The team configured HubSpot in parallel with the data migration. This included building the new deal pipeline with seven stages, creating 15 custom reports and three dashboards, setting up lead scoring based on the criteria previously used in Salesforce, configuring automated workflows for lead assignment and deal rotation, and connecting the eight existing integrations (Slack, Zoom, Gong, LinkedIn Sales Navigator, DocuSign, Stripe, Intercom, and Google Workspace).

Phase 3: Training, Testing, and Go-Live (Days 61-90)

The final month focused on ensuring the team was ready to work in HubSpot on day one of the switch. The company ran both systems in parallel for two weeks, with the sales team entering data in HubSpot while Salesforce remained read-only for historical reference.

Training was delivered in three tiers. Sales reps received four hours of hands-on training covering daily workflows: logging activities, managing deals, using sequences, and running personal reports. Sales managers received an additional two hours focused on pipeline reporting, forecasting, and team performance dashboards. The sales ops team received eight hours of admin training covering workflow creation, property management, and integration maintenance.

The go-live date was set for a Monday. The previous Friday, the team performed a final data sync to capture any records created during the parallel period. Salesforce access was restricted to read-only on the following Wednesday, and fully decommissioned 30 days later.

Key Challenges and How They Were Resolved

No migration goes perfectly. Here are the five biggest challenges the team encountered and how they resolved each one.

Challenge 1: Data quality issues. The Salesforce instance contained 340,000 contacts, but analysis revealed that 28 percent had missing email addresses, 15 percent were duplicates, and 9 percent had bounced email addresses still marked as valid. The team spent two full weeks on data cleaning before beginning the migration. They used a combination of automated deduplication rules and manual review for high-value accounts. The final migrated dataset was 245,000 contacts, a much healthier and more actionable database.

Challenge 2: Workflow logic differences. Salesforce workflow rules and process builder automations do not translate directly to HubSpot workflows. The team had to rebuild each automation from scratch, adapting the logic to HubSpot's enrollment triggers and action framework. Three automations required significant redesign because HubSpot handles lead assignment differently than Salesforce. This added an unexpected week to the configuration phase.

Challenge 3: Historical reporting gaps. While deal data and activity logs were migrated, some historical reporting context was lost in translation. Salesforce report formulas and custom report types do not exist in HubSpot, so the team had to recreate reporting logic using HubSpot's custom report builder. For the first quarter post-migration, the team maintained access to a Salesforce data export in a spreadsheet for historical comparisons.

Challenge 4: Sales team resistance. Despite leadership buy-in, several senior sales reps were resistant to the change. They had spent years building their workflows in Salesforce and were reluctant to learn a new system. The company addressed this by identifying two sales reps who were enthusiastic about the change and designating them as "HubSpot champions." These champions provided peer support, led informal training sessions, and helped reluctant reps adapt during the first month.

Challenge 5: Integration reconnection. Three of the eight integrations required custom API work to reconnect with HubSpot. The Gong integration, in particular, needed a middleware solution because the native HubSpot-Gong connector did not support all the data fields the team required. This added $3,500 in one-time development costs.

Data Migration Strategy in Detail

The data migration strategy deserves a deeper look because it is the area where most CRM migrations fail. The team followed a structured approach that prioritized data integrity over speed.

First, they created a complete field mapping document that listed every Salesforce field alongside its HubSpot equivalent. Custom fields that did not have a direct HubSpot match were created as custom properties in HubSpot before the migration began. This mapping document served as the single source of truth throughout the project.

Second, they performed three test migrations before the final migration. Each test migration involved importing a subset of 5,000 records and validating that all fields, relationships, and activities were correctly transferred. The first test migration had a 23 percent error rate, mostly due to date format mismatches and picklist value inconsistencies. By the third test migration, the error rate was below 1 percent.

Third, they used an incremental migration approach rather than a big bang. Companies were migrated first, then contacts, then deals, then activities. Each object type was validated before proceeding to the next. This sequential approach made it easier to identify and fix issues at each stage rather than dealing with a tangled mess of errors across all object types simultaneously.

Results After Six Months

Six months after completing the migration, the company measured the impact across several dimensions.

Cost savings: The total annual CRM cost dropped from $72,000 to $54,000, a savings of $18,000 per year. Additionally, the company eliminated $24,000 per year in Salesforce admin consulting fees because the sales ops team could now manage HubSpot configurations independently. The net annual savings totaled $42,000.

Sales productivity: The average time sales reps spent on CRM data entry decreased by 35 percent. Deal creation time dropped from 4 minutes in Salesforce to under 90 seconds in HubSpot. The time to generate a pipeline report went from 45 minutes (requiring admin help) to 10 minutes (self-serve by any manager).

Adoption rates: CRM adoption among sales reps increased from 62 percent (measured by daily login and activity logging rates in Salesforce) to 94 percent in HubSpot. The improved interface and mobile app were cited as the primary reasons in internal surveys.

Marketing-sales alignment: With marketing and sales on the same HubSpot instance, lead handoff became seamless. Marketing-attributed revenue increased by 22 percent in the first two quarters post-migration, primarily because attribution tracking was now accurate and complete.

Pipeline visibility: The VP of Sales reported that forecasting accuracy improved by 15 percent because deal stage definitions were cleaner in HubSpot and the team was more consistent in updating deal properties.

Lessons Learned and Recommendations

Based on this migration, here are the top recommendations for any company considering the same move.

Invest heavily in Phase 1. The planning phase is the most important phase. Every hour spent auditing your Salesforce instance and mapping data saves multiple hours of troubleshooting during the migration itself. Do not rush this step.

Clean your data before you migrate, not after. Migrating dirty data into a clean HubSpot instance defeats the purpose. Deduplicate, validate email addresses, and archive inactive records before you begin.

Run test migrations. Never attempt a one-shot migration with your full dataset. Run at least two test migrations with subsets to identify field mapping issues, date format problems, and relationship mismatches.

Designate change champions. Peer influence is more effective than top-down mandates for driving CRM adoption. Find enthusiastic users and empower them to support their colleagues.

Maintain read-only Salesforce access for 30 days. Do not decommission Salesforce immediately. Your team will need to reference historical data that might not have migrated perfectly, and having the old system available as a safety net reduces anxiety during the transition.

Frequently Asked Questions

How long does a Salesforce to HubSpot migration typically take?

Most mid-market migrations take between 60 and 120 days depending on data volume, complexity of custom objects, and the number of integrations. The 90-day timeline in this case study is representative of a company with moderate complexity (250K contacts, 8 integrations, standard custom objects). Simpler implementations with fewer than 50,000 contacts can often be completed in 45 to 60 days.

Will I lose data during the migration?

You should not lose data if the migration is properly planned and executed. The key is creating a comprehensive field mapping document, running test migrations, and validating data at each stage. However, some metadata like Salesforce report configurations, dashboard layouts, and workflow rule logic cannot be automatically transferred and must be manually recreated in HubSpot.

How much does a Salesforce to HubSpot migration cost?

Direct costs vary widely. HubSpot offers free migration support for qualifying enterprise customers. Third-party migration services typically charge between $5,000 and $25,000 depending on complexity. Internal labor costs (staff time for planning, testing, and training) are often the largest expense. In this case study, the total migration cost including the external specialist, integration development, and internal labor was approximately $35,000, which was recouped within 10 months through cost savings.

What is the biggest risk during a CRM migration?

The biggest risk is loss of pipeline visibility during the transition period. If deal data is not migrated accurately or sales reps are slow to adopt the new system, leadership can lose sight of the sales pipeline for weeks. Mitigate this risk by running systems in parallel, validating deal data thoroughly, and ensuring reps are trained before the go-live date.

Should I hire a migration consultant or do it in-house?

For companies with more than 100,000 contacts or significant custom Salesforce configurations, hiring a migration consultant is strongly recommended. The consultant brings experience with common pitfalls, field mapping best practices, and testing methodologies that save time and reduce risk. For simpler Salesforce instances with standard configurations, an experienced internal ops team can often manage the migration with guidance from HubSpot's documentation and support.

Conclusion

Migrating from Salesforce to HubSpot is a significant undertaking, but the results in this case study demonstrate that the investment pays off. A 90-day timeline is achievable with proper planning, dedicated resources, and a phased approach. The company in this case study saved $42,000 annually, increased sales team adoption from 62 to 94 percent, and achieved seamless marketing-sales alignment that drove a 22 percent increase in marketing-attributed revenue.

The keys to success are thorough planning in Phase 1, meticulous data cleaning before migration, multiple test migrations to catch issues early, and proactive change management to drive adoption. If your team is struggling with Salesforce complexity, rising costs, or disconnected marketing and sales systems, HubSpot offers a compelling alternative that delivers measurable ROI within the first year.

Start by auditing your current Salesforce instance and building a field mapping document. From there, request a HubSpot demo tailored to your specific use case, and explore whether their migration support program can help accelerate your transition.
