Our database size is 250GB and I am planning to migrate from 6.7.7 to 7.9.1 . In order to speed up the upgrade process, I would like to know if it there is a way to perform a clean up.
Welcome to the community!
I’m glad to see you’re planning your upgrade. You might go ahead and jump to 7.9.2, which is the latest point release of the LTS.
Regarding your database, we worked hard to make sure the upgrade process runs in a reasonable time, so I can only recommend normal maintenance/hygiene, unless you have a lot of old projects sitting around that you are ready to delete anyway.
