Hello Christian,

 

Did you ever get an answer to that question ?

The procedure does not mention any requierment to change the partition onf the VM.

Quid ?

Thanks for the feed back Christian.

 

We are actually running 8.6, butit seems we still need to do a fresh install after the upgrade to restore the data onto it. This is due to the fact that Cisco recommends 1 HD of 110Gb for version 9 while we run on 2 HD of 80 Gb on 8.6.

 

Cheers,
