	Can't guarantee anything in this business (*)

	But I have done it several times now.  Three servers, 1.2.11 -> 1.4.0,=20
and then later 1.4.0 -> 1.4.1.  In the first case, the servers were done=20
several months apart.

	I tried to minimize the impact by migrating most of the volumes off the=20
server before each upgrade, so users were not impacted at all.=20
Obviously, that requires having sufficient free space and time to move=20
the data around between upgrades.


(*) I did one server from home late on Saturday, but because I was also=20
upgrading the kernel at the same time, rebooted after putting the new=20
version in place.  The system never returned!  I had to come into work=20
the next day just to hit F5 to acknowledge the RAID controller's=20
complaint about a failing disk in the RAID-5 array.  Good thing I moved=20
the users' volumes off first.
