I am trying to upgrade from CUCM version 6.1.1a ( to through Software Installation / Upgrade. The database I'm working with has a cluster with the publisher and subscriber, but for now I'm only upgrading in laboratory the publisher. The upgrade seems ok , in the end he says he did the upgrade but when I try to switch-version got the following error "error: after sync switch version failed."
However doing the "> switch-version nodatasync", the call manager is reset and climb the right partition and apparently did well to upgrade, at least I can check the database and the objects are there. Anyone know if there are any implications of using the command nodatasync? Or what does the command nodatasync?
