Upgrading BIGIP 2000S to R2600

Hi, 

I have a pair of BIGIP 2000 licensed with LTM and need to upgrade the hardware to R2600. I  have some backend nodes pointing to F5 as their gateways. 2000 appliances run code v15.1. Will it be doable to archive CSF file of old F5s, edit some names related to 2000s like hostname and license with new names of 2600s, load the file on new F5s? I'm thinking to use different mgmt IP but keep all other configuration of VS, Vlans, IPs as they are.

Also, what about license and certificate files?

Thank you!
