I am facing an upgrade from CUCM 5.1 with the System Version 126.96.36.19932-1 to 7.1(5)
I can't find this particular release in the compatibility matrix:
so I am a little bit afraid, cause it might be an engineering special or something like this.
I can't find anything after 5.1(2b), which is 188.8.131.5200
I think I have to go through 5.1(3f), which is the "newest" version supporting upgrades from 5.1.2 and then go directly to 7.1(5).
Any hints are welcome.
