As I contemplate upgrading all my old filers from 4.x to 5.x, I was wondering what the horror stories are out there. Or is this truly a simple upgrade?
The only problem we've had is the result of subtle changes to the dump/restore commands.
The dump command changed slightly if you use the blocksize option. The restore command now outputs additional text that screwed up some of our restore scripts.
All in all - it's the most painless OS upgrade i've ever done.
