You can refer below upgrade

You can refer below upgrade guide, it will help you to plan perfectly.

You need to request the license via Product Upgrade Tool, you need to get converted DLUs to UCL/CUWL from Cisco as per your requirement, license structure has changed in 9.x and later.

CUCM 10.0 and beyond is only supported in a virtualized deployment so you need to take care of it.

Hi Siva,


Basically, PCD is an pplication used for migration of legacy CUCM clusters version 6.1.5, 7.1.5 , 8.x to new VM based servers.Also, to change IP address on CUCM 10, switch versions,reboot and install COP files.


In your case, u can upgrade to 10 even without PCD. Just need to check the compatibility matrix.

1-As mr/Aman , you will need to purchase UCSS for 1 or 3 years up to youfrom one of the Cisco parteners resellers , which allow you to do upgrade ,then you can purchase as optional ESW which is useful to contact TAC for any upgrade Bugs .After that we can do convert from DLU to UCL via the product upgrade tool (PUT). Keep in your mind 6 DLUs converted to 1 X UCL.
