Hi All

Just checking through documentation for CUCM 10.5 for an upgrade, the
compatibility guide states that a direct upgrade is from 8.6.1 onwards as
shown below.

However in the Read Me notes for 10.5.2 Su1 it states the following


 *Version and Description*

This SU is a cumulative update that incorporates all of the fixes and
changes from Cisco Unified Communications Manager 10.5(2) along with
additional changes that are specific to this SU.

*Note*

You can only install this SU on Cisco Unified Communications Manager
Release 6.1(4x), 6.1(5x), 7.1(3x), 7.1(5x), 8.0(x), 8.5(1x), 8.6(x),
9.0(x), 9.1(x), 10.0(1), 10.5(1), or 10.5(2) This SU will not install over
any 10.5(2)ES’s. Upgrades from 6x, 7x, 8.x, and 9.x need to be requested
via PUT (www.cisco.com/upgrade) to obtain the necessary license. This SU
should not be installed on a Business Edition 3000 server.

I would normally always go with what is says in the compatibility matrix,
however my colleague has just done an upgrade albeit in a lab from 8.5.1
direct to 10.5.2 SU1.

Anyone know if he just got lucky or if that is now supported?

Regards

Nick
