[cisco-voip] UC and UCCX 9.x upgrade to 11.5 sequencing question - when to upgrade to ESXi 6

[Charles Goldsmith]

Personally, I'd wait and do the bios/cimc and vmware until after the
upgrade.  Otherwise, I'd want to test 9.x on 6 in a lab to make sure there
are no gotchas, but personally, I'd rather stay on a supported platform, in
case you do run into issues and need TACs assistance.

I also wouldn't change linux type until the upgrade guide tells you, and
keep in mind, you may need to redo the vmnic drivers, depending on how old
the OVA was that built the system, the 10.x upgrade and higher has you
changing to vmxnet drivers.

At what version did we get the partition alignment?  Can't remember if that
was 9.x or 10.x, but if it's not on 9.x, that could also be a concern,
depending on what OVA originally built the system.

Just my $0.03 worth
