any help is highly appreciated

Are we going in right track?IF yes what will be the best approach to build new ISE cluster without impact old environment

or we can go any alternate plan to resolve the cpu cores 4 and disk space issue.

I recommend reading the installation guide. In theory you can build an ISE node with any range of cpu/RAM etc. BUT Any deviation from the official Cisco document is not recommended because it either won’t work well or won’t be supported. Just build it as indicated. Small/Medium is typical build for PAN/MnT/PSN. Now there is also a large VM for special MnT cases.

I recommend the Cisco Live session - Designing ISE for Scale & High Availability - BRKSEC-3699 from Melbourne 2019
