Call Manager 8.0 to 9.1 upgrade

[Richard Dumag]

We are currently running Call Manager 8, UCCE 8, and CVP 8. ICM/CTI 8. 

We would like to upgrade Call Manager 8 to 9.1 first before upgrading UCCE, CVP, etc., it could be months before these are upgraded.

Does anyone know or foresee any issues if UCCE, CVP, etc., are not upgraded right away after CM is upgraded?

Any comment is appreciated.  Thanks.

Look at the UCCE compatibility matrix as you need the exact versions to find out whether they will work together, of ir you'll need a single window on which to upgrade all.
