recently it kept failing, Turned out CUC replication wasn’t set up correctly. Ran the command from the Pub and it stated everything was good, Ran from the Sub said it was failed. Ended up re-building the CUC Sub. The issue came about from a host name change
years back and some of the tables where not updated on the sub.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I will say one thing, if you have the opportunity to duplicate the environment in an off-line network and perform the upgrades there, then your migration will basically be downtime involved with shutting down old servers
and turning up new servers. This is not trivial, by any stretch of the imagination. However, once you put some thought into it, I think you’ll find this method extremely valuable.

<p class="MsoNormal"><span lang="EN-US">You work out all the kinks in the offline network and repeat until you are satisfied.
