[cisco-voip] CUCM6 MCS to 8.6 UCS bridged upgrade Question

[Terry Cheema]

Liaise with Cisco licensing team (licensing at cisco.com). They will rehost and consolidate all license files into one, So during the migration you will need to upload just one license file.

Once you do a DRS restore it will also restore those old license files as well. I have been deleting all the old license files and then upload new license file. It cleans up the new system from obsolete license files.

You can list and delete all the old license files before you upload new from cli by below command:

File list license * 

And to delete:

file delete license * noconfirm

By using wildcard * you dont have to delete files one by one, With no confirm option you dont have to confirm everytime.
