ISE Upgrade 2.2 -> 2.6 and backup/restore to pre-prod environment

Hi team,

 

Customer, a large bank, is preparing to upgrade his 12-node SNS3595 deployment from 2.2 to 2.6 with our partner and they want to test out the upgrade process in their pre-production VM environment.

 

They want to backup/restore the production to the pre-production with current 2.2 version to have the same database and run the URT tool to get a preview of the upgrade readiness. They would then re-image the nodes with 2.6 (start new OVAs) and restore the 2.2 DB to 2.6 and test out as well the go-back procedure. If this all works they will do the same in production and get an estimate also of the time required.

 

The pre-production environment however has a few minor differences vs the production: different AD join point, SAML config and log destinations. Will this cause the URT tool to fail?

 

Is there also a firmware dependency for the SNS-3595 for this upgrade?

 

Thanks
