We are preparing for a migration of Nexus database from Orient to PostgreSQL. After reading about as much information as I could find, I’m still left wondering how long this migration is expected to take. Does anyone have experiences to share with how long the migration took? I need to schedule downtime, which will be much easier with an accurate timeframe.
We are working on creating a replica of our current server with a backup that can be used to test this, but that’s going to take some time.
It varies a lot by size, but the conversion really only affects the content of the database that stores configuration and the list of binaries stored by Repository. The binaries themselves aren’t moved or transformed.
If you just want to check on timing, you should be able to test the meaty part of the procedure for yourself just with a database export as input, without having a replica of the live server itself or any access to a copy of the binaries.
