6500 cluster rollback

[mooo_]

Hello

I'm going to upgrade our 6500 Active/Passive cluster with central manager.

If something happen and I will need to do a rollback... do I need to break the cluster before the rollback ? Guy from JTAC told me that I need to do so, but I can't find any mention about this anywhere in the documentation...

As far as I know the rollback should affect the whole cluster so I don't see any reason to break the cluster.

Thanks for help

Last Friday, I rolled back an active/passive cluster of SA6000's from 6.5r4 to 6.3r4.  I did not break the cluster beforehand.  Can't promise it always works, but did for me.
