I am starting to make a plan on how we can make the planned database migration as smooth as possible.
I ran some tests and the migration itself will take less than 2 minutes.
Propagating the DNS for the new server instance is normally done really quickly and should take almost no time.
I anticipate that the whole process will be done in 5 minutes.
During this 5 minute period Futureland will be in a read-only state which means all of the journals and entries will still be publicly available, but writing operations like publishing entries and creating new comments will not work and result in errors.
The goal is to effect our users as little as possible, so I looked up in which hours and on which weekdays our users create the least amount of entries. The result is Saturday from 8 am till 9 am UTC. This gives me the perfect opportunity to migrate the database next Saturday between 3 pm and 4 pm in my current timezone.
