UCCX 11.6 upgrade

[dannoofWI]

To take advantage of some features and fixes we would like to upgrade from UCCX 10.6.2 to 11.6.2.

However we would like to hold off on CUCM and stay at 10.5 until later when we will move the whole UC to version 12. From the UCCX compatibility matrix it looks like this would be ok.

Has anybody done this and what should we watch out for?

Thanks

Dan

Yep, that combination is allowed.

The main thing I have heard of is browser compatibility now that they require WebSocket support in v11; an older browser (ie IE Compatibility Mode) can really drag the server down performance-wise.
Also ensure you apply the latest ES published on Cisco.com after upgrading. At this point they are defacto SUs for CCX.
