We have CUCM 7.1.5.33900-10 installed on two MCS 7825I4 and UCCX 8.0.2.11004-12 installed on two MCS 7825I4.
We want to upagrade and migrate to BE6000 version 10x.
I’ve read that: “for MCS7800 to BE migrations, the included virtualization license is not compatible with Cisco Prime Collaboration Deployment (PCD). Use FND, ST,ET,EP if you plan to use PCD” So, Am I right that in this case we should perform jump upgrade via virtual lab server? And we can't use PCD?
And if I understand correctly, that our upgrade/migrate steps are:
Install all unused licences
Perform DRS backup from CUCM and UCCX on MCS servers
Do CDR purge
Install cucm 7.1.5.33900-10 and 8.0.2.11004-12 in virtual lab server
Perform DRS restore (see step 2)
Apply phone firmware for cucm 10 release
Upgrade virtual lab server (CUCM and UCCX) to release 10
