Upgrade Order - CUCM, CUC, & CUP

 

Customer has a virtual CUCM, CUC & CUP environment running on 2 hosts in the same chassis.  CUC & CUP are misbehaving due to known CPU utilization bugs and will be upgraded to latest SU.  Question is what to upgrade first?  CUC is the most unstable, so upgrading it first was my initial thought, then CUP and CUCM last.  Is there any reason to change this order of updates?

 

CUCM 8.6(2a)SU2     update to 8.6(2a)SU5

CUC 8.6(2a)SU3        update to 8.6(2a)SU5

CUP 8.6(5)                 update to 8.6(5)SU3

 

 

I appreciate it,

 

Beau

You can upgrade CUCM or CUC in either order based on the versions you provided.  CUP should be upgraded after CUCM has been upgraded.
