Friends,
I am in the process of Virtualize the CUCM 9.1 cluster from MCS to UCS. I have a plan to upgrade to 11.5 also.
I never done this before, I know, this is critical , needs lot of pre work.
Anyone done this virtualization ? what is the best way of doing this, to have minimal downtime and succesful migration?
PCD migration is the good option or Can I do DRS backup and restore.
Note : we decided to keep same IP address and hostname.
Please share your thoughts and experience , that really help for me.
