hi again!
well I could not export and import configs from 7.1.5 to 8.6.2 because of a huge amount of errors.
now I try to understand how I can upgrade my test CUCM 7.1.5 to 8.6.2
I tried to start the VM with 7.1.5 from the connected virtual DVD with bootable 8.6.2.
but it asks "do you want to rewrite the disk?"
and it's not what I want to do.
what is the right way of uprgrading from 7.1.5 to 8.6.2?

Hi,
To upgrade on the same hardware, you do not boot from disk. The simplest way for you to proceed would be to insert the disk when CUCM is running, browse to CUCM OS Administration and navigate to Software Upgrades > Install/Upgrade.
There are several ways of performing the upgrade and recommend you review the below before proceeding.
