How to switch from Pi.
Moving away from Pi means re-creating project instructions and rules, re-adding MCP servers and other tool connections, and adjusting how your team reviews agent output. Run a pilot on a branch of a real repository before committing.
- Export a sample of your data and test an import into the new product.
- List the automations, integrations and permissions you would need to rebuild.
- Pilot with one team before a full cut-over.
- Check contract terms and notice periods with the current vendor.
