Hi everybody, I would like to upgrade my current cucm 7.1.5 to be6k 9.1.2 on new servers. First of all is it a recommended upgrade path using jump upgrade? On is it much safer to start a new clean installation? If i choose the jump upgrade i would like the license from my old cluster that will be converted to cuwl to be valid on the old cluster as long as i need to build configure the new cluster + the cuc. In term of software what i will need bootable cds etc ? Which is the safest path that you recommend?

You won't do anything with licenses during the jump upgrade, until you've finished the last step of the DRS into fresh installs. That's when you'll need to engage licensing to migrate what you have on 7.1(3) to 9.1(2).
Yes, you'll need install media for your CUCM 7.1(3) version, as well as for 9.1(2).
If i decide to go with a clean installation, which is much safer. Is it possible to built a second similar cluster with the same numbering plan connected trough a trunk and perform a phased migration approached branch by branch? What do you believe is it worth it?
Hi there, after 2 days of experimentation i manage to upgrade my cucm 7.1.5 to 9.1.2 pub. Next week i will do the subs! The only problem i had was a bug that i was hitting that did not let me upgrade to 9.1.2! Thank you all for your answers!!

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
