I need to stop thinking about my little personal coding projects a potentially useful and see them as they truly are: the modern equivalent of building ships-in-a-bottle.
Alrighty..! I think I got it all ready for the migration 🤔
New server within local (mstdn) network
Setup new Mastodon server that's ready for a database import
On new server:
Smaller main server
Scalable volume for database
Scalable volume for search db
Scalable volume for extra backups
Now I'm waiting for a good moment to power down Mastodon, start backups and wait for that until that backup can be reimported on the new server via the volume!
