Cisco ISE Upgrade

[aehtibarov]

Hello friends, 

I am trying to create new node with latest version of ISE and restore backup from old deployment.

Do I need to restore backuped config to psns and secondary admin node before registering in new deployment?
Or is that enough restoring backup to only PAN node and register other nodes so they will take configurations automatically?

If you register other new nodes with the same version the config will sync from the PAN in the new deployment.

Just to add what Marvin said - you build a fresh ISE node and then you must restore the config backup into that node while it's still in STANDALONE node (i.e. not yet promoted to Primary). One back has been restored, you will promote it to PRIMARY. Only then can you register additional nodes to that Primary.
