HubSpot data migration cost is one of the most underestimated parts of a HubSpot implementation. At Cogent, migration is a fixed-price add-on in three sizes: £2,500 for one simple source such as a spreadsheet, £5,000 from an existing CRM or a few sources, and £10,000 for complex or high-volume work across several systems or a lot of history. The biggest single factor in how much work a migration involves is the quality of your existing data. Dirty data adds cleansing work, whether you do it before or during the migration.
Data migration isn’t just moving files from one system to another. It means rebuilding your customer database within HubSpot’s structure while preserving relationships, historical records and business logic. Below are Cogent’s prices, the five factors that drive the work, and the costs that catch people out.
How much does HubSpot data migration cost?
Cogent prices HubSpot data migration as a fixed add-on to a HubSpot implementation, in three sizes set by how many sources you are moving from and how much history comes across. The implementation itself is a Level package of £15,000 to £20,000. Migration is added only where the scope needs it, and every price is agreed before work starts.
| Migration size | What it covers | Price (fixed) |
|---|---|---|
| Small | One simple source, such as a spreadsheet | £2,500 |
| Existing CRM or a few sources | Moving from a CRM you already use, or combining a few sources | £5,000 |
| Complex or high volume | Several systems or a lot of history | £10,000 |
If HubSpot also has to connect to a system that no OW Sync connector covers, a custom connection is £3,000. For how migration fits into the total price of a project, see how much HubSpot implementation and integration costs.
Why does data quality drive the cost?
The condition of your existing data determines migration complexity more than any other factor, including volume. Clean, well-organised data can be migrated efficiently regardless of size. Poor-quality data needs extensive manual work even in small volumes, and that cleansing happens whether you do it before or during the migration.
Migrating messy, inconsistent data takes significant agency time to cleanse, which increases costs and slows the process down. This isn’t optional preparation; it’s essential work.
These are the things that make data “dirty”:
- Duplicate contacts with different spellings
- Missing company associations
- Inconsistent field formats (phone numbers, addresses)
- Incomplete records
- Outdated information
- Data spread across multiple systems
If duplicates are your main problem, how to fix data duplication issues covers where they come from. An audit before you migrate shows how much cleansing you need; how much a HubSpot audit costs sets out the options.
What are the five factors that affect the price?
Five factors drive the price of a HubSpot data migration: how complex your source system is, how much data and how many object types you are moving, how much history you need to keep, how many integrations have to work afterwards, and how much the data has to be transformed to fit HubSpot. Each one adds time, testing or both.
| Factor | What pushes the cost up |
|---|---|
| 1. Source system complexity | Enterprise or legacy systems rather than spreadsheets |
| 2. Data volume and types | More objects, more records, custom objects |
| 3. Historical data requirements | Years of email history, call logs and activity records |
| 4. Integration needs | More connections, especially custom ones |
| 5. Data transformation | Complex restructuring and high data volumes |
1. Source system complexity
The CRM you are migrating from plays a significant role. Different systems may need different migration methods, such as API-based transfers or manual imports, each varying in complexity. Simple migrations from spreadsheets cost less than complex enterprise systems like Dynamics or Salesforce, and legacy systems often need custom extraction methods that add time and cost.
2. Data volume and types
The number of objects being migrated is a critical factor, because each object adds to the workload. The volume of records within each object affects pricing too: more records mean more data to handle, which adds complexity and time. Standard objects (contacts, companies, deals) migrate straightforwardly. Custom objects need additional configuration and testing.
3. Historical data requirements
Historical data retention can substantially increase complexity and cost, particularly for businesses in regulated industries or with long customer relationships. Migrating years of email history, call logs and activity records adds substantial time to the process.
4. Integration needs
Each connection to another software system, especially a custom one, adds complexity and cost. Your accounting system, marketing tools and operational software all need to work with HubSpot after migration. At Cogent, a custom connection to a system with no OW Sync connector is £3,000. Cogent’s integrations service covers connecting HubSpot to ERP, finance and other back-office systems.
5. Data transformation requirements
Data transformation means converting data from one format or structure to another, such as merging multiple properties to match HubSpot’s data structure. It is scoped on the complexity of the transformations and the volume of data.
How long does a HubSpot data migration take?
A standard migration, for example from Pipedrive to HubSpot, takes about 8 weeks. Custom objects, multiple tools or large datasets (1M+ records) may take up to 12 weeks. Rushed timelines increase costs significantly, because migration teams need adequate time for testing, validation and fixing issues.
| Migration type | Typical timeline |
|---|---|
| Standard (e.g. Pipedrive to HubSpot) | About 8 weeks |
| Custom objects, multiple tools or 1M+ records | Up to 12 weeks |
What hidden costs should you budget for?
Three costs are easy to miss when budgeting for a migration: data cleansing, recreating your reports in HubSpot, and training your team to use the new system. Each is priced on its own drivers, so ask for them to be shown separately on any quote you receive.
Data cleansing services
Data cleansing includes email validation and deduplication. Email validation is priced on the number of contact records to be validated. Deduplication pricing depends on the number of objects that need consolidating, the total number of records and the number of rules applied.
Report recreation
Recreating reports from your current CRM in your HubSpot portal can affect the price. The complexity of the reports and the number of dashboards or reports needed are the main factors.
Training and adoption
Training and ongoing support are among the most commonly overlooked expenses in a CRM project, alongside the migration itself. Leaving them out of the budget can force you to cut corners on the parts of the project that decide whether your team actually uses HubSpot.
Should you migrate in-house or use a partner?
Doing the migration in-house is rarely the cheap option it looks like. A proper migration takes a substantial amount of your team’s time, and every hour of it is time your people are not spending on revenue-generating work. No invoice arrives, but the opportunity cost is real. Professional migration reduces the risk of frozen pipelines, confused sales teams and lost momentum.
| In-house | Partner | |
|---|---|---|
| Effort | A substantial block of your team’s time | Partner time, scoped and priced up front |
| Cost | Opportunity cost of your team’s time | With Cogent: £2,500 (small), £5,000 or £10,000 (complex), fixed |
| Risk | Frozen pipelines, confused sales teams, lost momentum | Reduced by proper testing and validation |
The decision isn’t whether to migrate. It’s whether to do it right the first time. In The Cogent Blueprint™, data migration is mapped in the Confirm phase, before anything is built, and carried out in Deploy. To get a migration quote based on your own data, see data migration or book a call.
Questions people also ask
Is it cheaper to clean my data before migrating to HubSpot?
Yes. Cleansing is essential work that happens whether you handle it before or during migration. Messy, inconsistent data needs significant agency time to cleanse, which increases costs and slows the process. Clean, well-organised data can be migrated efficiently regardless of size, so tidying records first is where the savings are.
Does migrating from Salesforce or Dynamics cost more than from spreadsheets?
Usually. Simple migrations from spreadsheets cost less than complex enterprise systems like Dynamics or Salesforce, and legacy systems often need custom extraction methods that add time and cost. Different source systems may need API-based transfers or manual imports, each with its own level of complexity.
Do I have to migrate all my historical emails and call logs?
Not necessarily, and the decision affects the price. Migrating years of email history, call logs and activity records adds substantial time. Historical data retention can substantially increase complexity and cost, particularly for regulated industries or businesses with long customer relationships, so agree what history you actually need before the migration is scoped.
Can my own team do the migration to save money?
They can, but it is rarely free. A proper migration takes a substantial amount of your team's time, and every hour they spend on it is time not spent on revenue-generating work. That opportunity cost comes on top of the risk of getting it wrong: frozen pipelines, confused sales teams and lost momentum.
