[cisco-voip] UCCX Virtual 9.0(2) to 10.6(1) Upgrade

[Andrew Grech]

Thanks Dan I just checked the OVAs and I do need to change the vNIC I
remember doing this for another product but it wasn't documented unlike ccx
unless I'm missing it.

My other concern is my signed certificates but I have access to the CA so
its not a game changer if I need to reissue.

I have thought about running sandbox servers up in my lab loading a drs
then upgrading. I could then disconnect the NICs of the current vms and
move the sandbox servers into production. This would provide an easy
rollback. Anyone have experience with this? Note I won't be cloning the
sandbox servers from production but rather running them up from scratch.

official documentation, changing the vNIC to VMXNET3 through PowerCLI
should be done post-upgrade.

machine settings should be modified first, followed by the upgrade, then
wrapped up with the vNIC change to VMXNET3. I can provide documentation if
needed - it seems that UCCX documentation differs.
