Yup. I've done this many times with no problems.

Don't presume that because it's EXT3 that fscks are no longer necessary.
Only thing the journal guarantees is that your metadata won't become
corrupt (i think journal=data mount option fixes this but will affect
performance and not neccessarily badly). If your filesystem has been
shutdown cleanly many many times you could still has some loss. A fsck
should take care of that.

It's pretty straight forward. Did I mention to make sure you have backups?
Oh and the other concern is that you want to make sure you backup before
you get carried away ;-)

Can you tell my tape drive has saved my life and my job once or twice ;-)
