A real-world production migration from DigitalOcean to Hetzner dedicated, handling 248 GB of MySQL data across 30 databases, 34 Nginx sites, GitLab EE, Neo4j, and live mobile app traffic — with zero downtime.
Really good blogpost, as a sysadmin, this is a great way to handle a migration with zero downtime.
When I was migrating my servers to NixOS I did the same thing, I tried to make my configuration the same as the old OS so everything works cleanly, and it worked fine, but since it was all in the same server, I had to do manual migration for things like files and databases.
