Dear All,

What all needs to be considered for upgrading acs from 3.3 to acs 5.6..?\

Thanks

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
