Hi Prasan, you will need to be more specific for us to be able to provide you a better answer. Some quick things that come to my mind are:
1. ACS 5 now runs on Linux vs Windows
2. ACS 5 requires licensing (There is "base" for up to 500 devices and "large" for deployments with 500+ devices)
3. You cannot directly upgrade a 4.x node to 5.x. You will either need to re-build from scratch or use the migration utility
4. ACS 5 can cluster several ISE nodes in a way that you only configure from a single console and all of the configuration changes are replicated to the rest of the nodes
Here is a good link to review as well:

Thanks for that.
We have now migrated to 4.2.
We need to upgrade from 4.2 to 5.6. I understand that i should use migration utility since i need to migrate huge database and config.
Where i can download migration utility ..?

You can download the utility directly from ACS 5.x by going to System Administration > Download > Migration Utility
