If you care about the data, then you should back it up, both before this change and ongoing. You can take a snapshot of the filesystem, and then back up that snapshot while the server runs and modifies the live filesystem. Dump can do that automatically with "dump -L" (see the man page). Or, if that automatic snapshot is not enough to guarantee that the data is in a consistent state, you could bring the server down briefly to stop the filesystem action, take a snapshot manually, restart the server, and back up the snapshot while the system runs. Whatever you do, as you say, it would be good to test it on a spare server first, before messing with the live system. I suggest that you read relevant parts of the FreeBSD Handbook, including the chapter "Storage". <https://docs.freebsd.org/en/books/handbook/>;
