THE RIGHT APPROACH

Our tips for a successful Zendesk to HubSpot migration

Whichever solution you choose, here are a few recommendations drawn from our experience in the field:

  • Perform a complete export of your Zendesk data before starting the migration process.
  • Allow a minimum of 2 weeks' overlap during which your Zendesk and HubSpot licenses will run in parallel.
  • Maintain a safety margin of at least 10 days in relation to your target switchover date.
  • Don't opt for a partial migration if you need to recover your activities (emails, notes, history) : processing this data would then become much more complex and therefore more costly.
  • Remember to make an inventory of your existing Zendesk integrations, check for the existence of a native connector on the HubSpot side, and plan the development of customized integrations if necessary.
  • A change of tool that is so structuring for your organization is often the right time to challenge your existing processes before reproducing them, in order to gain in efficiency and strengthen collaboration between your teams.

Am I at risk of losing data when migrating from Zendesk to HubSpot?

Our top priority is the security of your historical data. Before any migration, we run a full export of your Zendesk data and define a detailed mapping plan. Depending on the chosen approach (HubSpot import tool, native connector, or custom import script), we make sure to bring over your tickets, contacts, companies, activities, and knowledge base. With a custom migration by Mi4, we filter, clean, and validate your data to avoid any critical loss.

How much data can we migrate, and which types of objects are supported?

We can migrate the core of your Zendesk environment: tickets, contacts, companies, activities (emails, notes, history), as well as your knowledge base. Custom import scripts allow us to remove the limitations of standard connectors and include your custom objects and fields, so you end up with a HubSpot structure that matches your existing processes.

How long does a migration take, and is there a transition period?

A full migration is usually planned over several weeks, depending on your data volume and the complexity of your Zendesk setup. We recommend at least 2 weeks of overlap during which Zendesk and HubSpot run in parallel, with a safety margin of about 10 days before the final switchover. This gives you time to test, train your teams, and fine-tune workflows without interrupting your support operations.

How is a custom migration with Mi4 different from a simple native HubSpot import?

Native connectors and import tools are fast, but limited: they don’t always handle full history, nor data cleaning or restructuring. With Mi4, you get end-to-end support: custom mapping plan, filtering and cleaning, rebuilding your pipelines, lists, and workflows, integrating your other tools, optimizing your processes, and training your teams. In short, you’re not just “importing data” — you’re moving to a HubSpot setup that is truly ready for your teams to use.
