Greetings,
I think I have a good handle on what I need to do but wanted to check for additional gotchas. We've got some 6290s that will replace some 6080. The 6290s are already built with their own root volume/disks and are running 8.1.2P4. The 6080s are running 7.3.5.1P4. I'm not planning on using the 6080 root disks so I'm not planning on upgrading the 6080s before hand. The plan is basically shut everything down, pull the 7.3.5 root disks, reassign all the other disks to the new system IDs and boot everything up.
It is my understanding that there is no 64 bit upgrade to aggregates/volumes that gets done automatically so I'm not seeing and issue there. I have functional /etc/rc, exports, hosts, and username.map files in place on the new hardware. I'm also going to have a copy of the old /etc directories on the new filers so I'll have everything there if I need to go back to them. All needed hardware is in the new heads and supported.
The new hardware has newer disk and shelf firmware but I'm going to let it do that during boot up. We have some MOOS drives that have been problematic so I don't want to do those before hand. We have no VM, very little cifs, and 1 SAN/FCP client. Other than that it is all nfs clients. I know I may or may not have to re-join the domain for the cifs piece but I can deal with that.
It seems this should be relatively simple and easy, but that's usually when I get into trouble :-) Any obvious holes/flaws in my plans that I should be aware of?
Thanks,
Jeff
