upgrade celerra to unisphere questions
I have two newer Celerra ns-120s. They are running running Dart 5.6.49.3 and flare code 4.29.000.5.006
Have a bunch of questions.
1) I have Celerra replicator V2 running. Is it OK to upgrade the target Celerra first and then upgrade the source at a later date? Can replication run with two different versions of Celerra?
2) I have the Unisphere service manager running and I see that it has the Celerra Upgrade Manager integrated. Do I update the Celerra /Dart code first (to 6.0.36.4) before I upgrade any flare code? It looks like this will work because the only error I can in the pre-upgrade health check is that the linux distro on the control station will be upgraded causing a longer upgrade time.
3) Can i upgrade the Celerra at a remote location over a fast WAN link (fast 45 Mb/s link)? I talked to one EMC engineer who was not sure. He thought I would have to have someone onsite in case something goes wrong. Since this is just a target and only used in case of disaster, I am not too worried if we have to open a ticket after the fact to get someone onsite.
4) And, while it looks like I can run this upgrade myself, is this something that requires a EMC support ticket and engineer on site? I opened a ticket before I realized I can download the tools myself. Just not sure what is officially supported by EMC.
Sorry bout so many questions. Thanks.

You might want to hold off a couple of days – DART 6.0.40.5 is just being released

Yes, DART and Flare are now customer upgradeable
Always upgrade DART first and then Flare
I haven tried it over a WAN but it should work if you have enough bandwidth.
Its going to drag a couple of hundred MB’s from the Windows box running USM to the Celerra – so if possible I would use a remote desktop session to a Windows server that is located in the DR site for the update. You don’t have to download the code twice – you can just put it into the correct directory for the code repository.
I think for replications the rule is to upgrade the destination first – but I would suggest to verify that with customer service
Have fun
