Best upgrade path

[John Huthmaker]

I have a publisher and subscriber 8.6 call manager.  I have a unity connect 8.6 server.  I have a presence 8.6 server, and finally I have a UCCX 8.5 server.  What is the best upgrade path?

I'm thinking that since UCCX 9 is compatible with CallManager 8.6 I can upgrade that first.  But rest is a gray area.  In what order should I upgrade these?  I have the entitlement for all of them.

CUC can be done at any time, but you do need to upgrade CUCM before upgrading CUPS to IM&P.

1. Upgrade CCX

2. Upgrade UCXN

3. Upgrade CUCM and IMP, update Jtapi on CCX

2 and 3 can be switched.

HTH,
