Upgrade CUCM from 6.1 to 9.1 Business Edition

Hi all,

 

I have to upgrade a CUCM  actually in use from 6.1 on MCS 7828  to CUCM 9.1 on VMWARE ( Business Edition on UCS C220).

 

I want to know what is the best scenario to do for the upgrade?

 

thanks in advance

 

regards

 

Cham

If you're a partner, see here

If you're a partner, see here the doc for 5K to 6K migration

Short answer, go to a version supported on ESXi (8.(0)2a+) on your MCS to migrate to UCS, then use BAT at any point in time you like to migrate the data.
