I know it's new, but has anyone seen issues w/ a direct upgrade from v11? Second question, should I expect issues w/ v12 on one server in a cluster and v11 on the second machine?
It's not possible to have 2 different versions of the QVS running in a cluster.
I've experienced this in the past, where you can't start the secondary node in the cluster unless it matches the primary node's version.
What situation are you hoping to address with this architectural direction?

Hi,
This is possible for testing.
All QVSs in a cluster must have the same build number and share the same document root. When upgrading to a new version of QlikView, this is normally not a problem, if all servers are stopped, upgraded, and re-started in one go. However, if not all servers are upgraded at the same time, the build number and document root have to be taken into consideration, since the original cluster is split into two sub-clusters during the upgrade process – one that runs the original version of QlikView and one that runs the new version of QlikView – until all servers have been successfully upgraded to the new version of QlikView. Both sub-clusters share the existing cluster license, including all CALs.
The process for upgrading a single server in a cluster to a new version of QlikView is as follows:
Settings.ini
file (normally located in the C:\ProgramData\QlikTech\QlikViewServer
folder) on the server where the new version of QlikView was installed.Bill
