CUCM 7.x to 9.x upgrade.

Hello all,

I have a fundamental question(s) regarding upgrade procedure of CUCM 7.x to 9.x version.

1.) Can I go through upgrade directly? with no need of 8.x upgrade first

2.) Does Cisco provide any valid procedure documentation for upgrade?

3.) Did anybody of you succeeded in upgrade upon virtual platform aka Vmware? If yes, any advice what should I avoid and what is on thye other hand mandatory?

 

Thanks for answers.

Randy
