Upgrading CUCM and UCCX from v8.51 to v10.0

[usmanghani255]

Hi,

We are upgrading UCCX (Contact Center Express) from 8.5.1SU3 to CCX 10.0 and for CUCM 8.5.1SU1 to CUCM 10.0

I want to confirm the steps in upgrading of CCX and CUCM. Eg,
Publisher CCX 8.5.1SU3 to CCX 8.5.1SU4
Subscriber CCX 8.5.1SU3 to CCX 8.5.1SU4
Publisher CCX 8.5.1SU4 to CCX 10.0
Subscriber CCX 8.5.1SU4 to CCX 10.0
then
CUCM Publisher 8.5 to 10
CUCM subscribers 8.5 to 10.

Or if there are any caveats for upgrade of both applications ???/

Thanks
