Thanks, Brian. So, basically, the upgrade in general is pretty straightforward.
The key point, though, is that I am promoting an important Amanda
client to be the new Amanda server. During that process, there may
be a period of time when the old server (running 2.5.1p3) will be
talking to this important client that has been updated to 3.3.0, but
not yet taken over as server. I don't want to miss backing it up
during that time.
So, briefly, will a 2.5.1p3 server have trouble with a 3.3.0 client
(just until I get things completely swapped around)?
I could fall back on the claim "amanda is generally compatible with
old releases", but that is not a lot of comfort without specific
experience. You may not need to run that gamut if you can briefly
run your backups with two servers.
Upgrade your new server (NS), comment it out of the disklist of the
old server (OS). Let NS back itself up as a client.
Upgrade one or a few of the other OS clients and make them clients
of NS. Eventually all OS will be backing up is itself and you
will have lots of experience upgrading clients and adding to NS.
That is when you finally do OS and again have a single server.
Beautiful, Jon!
That's perfect. I can gradually shuffle tapes over to the new system, and, eventually, all the tapes
and all the clients will be there. During the transition, I can recover stuff from either server
according to which was covering the period of time in interest for the client of interest.
Thank you,
