[cisco-voip] Upgrading CUCM from 8.5 to 10.5

[Nick]

Hi All

Thanks for your responses, I should have been more clear, I was referring
to a virtualised install on UCS servers already. I have always followed the
compatibility matrix and recently upgraded a 8.5.1 on UCS to 10.5 using an
interim step of 9.1.2, however my colleague then claimed he had tested in a
lab upgrade direct from 8.5 to 10.5.2 SU1 and pointed me to the second
section in my original email Version and Description which is taken from
the 10.5.2 SU1 release notes.

Now looking at the PCD notes that Dan has put in the link, I can see it
states the following

Upgrading from Releases 6.1(5), 7.1(3), 7.1(5), 8.0(1-3), 8.5(1), 8.6(1-2),
9.0(1), 9.1(1-2)

   1. If you currently have Releases 6.1(5), 7.1(3), 7.1(5), 8.0(1–3),
   8.5(1), 8.6(1–2), 9.0(1), 9.1(1–2) installed, you do not need to upgrade to
   an intermediate release. Complete the migration in the following stages:

So I guess the question is this also supported on a traditional style
upgrade already on UCS or just when using PCD?

Obviously with changing OVA specs etc, prior to upgrade.
