How to switch from Slack to an EU alternative

A three-step migration path that keeps your team running while you move to a European, GDPR-compliant european team messaging provider.

  1. Export your data from Slack. Use Slack's built-in export to pull configuration and customer data into a portable format. Keep this archive as the baseline you can roll back to.
  2. Pilot an EU-headquartered provider. Pick one provider from the list above and run it in parallel for a small project. Verify the features you depend on, sign a Data Processing Agreement, and confirm the EU data-residency claims on the vendor's sub-processor list.
  3. Cut over and decommission Slack. Migrate the rest of your data, update integrations, and switch DNS or config to point at the new provider. After a short overlap to verify behaviour, cancel your Slack subscription and update your records of processing activities.
