Hi,
I wanted to replace the existing 3315 hardware to 3415 or higher hardware.
The existing 3315 device is configured in standalone mode and I got 2 new 3415 and am planning to deploy in distributed mode.
What will be the best approach to migrate from 3315 to higher model in the below mentioned (high level) procedure. please suggest
Procedure 1 :
1. Make the 3315 as primary node.
2. Configure one of the 3415 hardware with 1.4 ise version and configure the device as secondary node.
3. Sync the configuration from 3315 primary to 3415 secondary.
4. And remove the 3315 from network.
Procedure 2 :
1. Configure 3415 with ise version 1.4.
2. Take the backup of existing 3315 and apply to 3415 device.
3. Shut the ports of 3315 and make the 3415 as the active device.
Procedure 3 :
1. Do a parallel built with 2 x 3415 device in distributed mode with different ip address.
2. Configure the New 3415 as the backup radius server.
3. Make all the network device to failover over to 3415 ise setup .
4. Remove the 3315 from the Network

hi,
Thanks for your suggestions, we have decided to buy 3595 appliances.
Is it possible to copy the configuration/backup from 3315 ISE 1.4 version and restore the backup on 3595 ISE 2.1 or latest version

You wont be able to restore 1.4 directly to the current recommend release, 2.4. It only supports backups taken from 2.0 and newer, so you would have to perform a jump upgrade. You could stand a node on 2.1, restore the 1.4 backup, then take the 2.1 backup and restore it on a 2.4 node.
Since you will be buying new nodes, it might be worth while looking at manually rebuilding the config, might take less time in a simple environment.
