opt/SVN section, what files can be removed?

Question

linux

Greetings. the /opt directory has run out of space. Our repositories are located in /opt/SVN - 1 size 1 TB.
Sorted, almost 450 GB is occupied by one of the repositories, /opt/SVN/m4fsvn, then "db/revs" occupies almost 310 GB. I understand that it is a DB.
What can be removed? because you need to free up space in /opt

Answer 1

Add places, transfer some data, with the help of links you can save path
PS how do random people know which repositories and data can be deleted from YOU?

Answer 2

See help for the commands below. MAKE A BACKUP. Make a cut to the desired version, or better a copy to the historical server. Test on test. Complete everything in combat.
