MySQL Mautic 6 to 7 Migration

I’m upgrading from Mautic 6.04 to the brand–new Mautic 7.0 instance and need every piece of data carried over—contacts, segments, campaigns, emails, the lot. Both installations sit on their own MySQL servers and the 6.04 database uses the standard Mautic schema; no custom tables or fields are in play. I already have fresh SQL dumps of the 6.04 site, so you can work from those or connect directly via SSH if you prefer.

Here’s what I’m expecting: a clean import into the 7.0 database, preserving IDs and relationships so the new instance behaves exactly as the old one. After migration I want to log in, spot-check a few contacts, open campaigns, and send a test email without errors in the logs. If you need to run phpMyAdmin, the MySQL CLI, or craft custom SQL scripts, that’s fine—as long as the final result is a fully functional Mautic 7.0 environment with all data intact.

Please let me know your proposed approach, rough timeline, and any precautions you’ll take to avoid downtime while you work.
