We currently have a GW 14.2.2 system all running on a single SLES 11 SP4 / OES2015 SP1 VM server. The techs that did the porting from a NetWare environment back in 2014 left the PO and MTA data structures on an NSS volume but the agents are running as linux agents.
We have a Novell Messenger 2.2 application running on the same server as GroupWise
In addition we have a mobility server running on a separate VM on SLES 11 SP4.
I want to upgrade everything to GroupWise 2018 and Messenger 2018. My understanding is that having the PO databases on an NSS volume is not optimal. My question is should I try to upgrade the server in place? If so, in what order? Do I upgrade SLES first then GroupWise or GroupWise then SLES?
Or should I spin up a separate SLES 12 server without OES, install GroupWise 2018 on it and then migrate the various databases from the current GroupWise server to the new one?
Can I upgrade the Mobility server first? Can I in place upgrade it to SLES 12 then upgrade the Mobility server to the latest?
