Hi Experts..
We are planning on migrate our customer CUCM then Upgrade it to 12.5 using PCD.
Our CUCM existing version is 10.5.2.13037-1
Here is my questions :
1. As seen from our CUCM version, we already did install the device pack
When migrating to the new VM clusters, Do i need to install the cop file as well or it is enough using iso file only with the matching Build patch code? (ex : 10.5.2.13037-1 using 10.5.2.13900-12 iso file)
2. When we upgraded to CUCM 12.5 version, what happen with ITL for each IP phone, do we need reset security for each phone? BTW our CUCM cluster is not secure..
Accepted Solutions
1. you need to use the iso image. u don't need to bother about the old device package. your new CUCM will have required firmwares. if you need the very latest u can load it later.
2. if you are using PCD, you don't need to.
