Cisco Wireless :: Replace 4402 With 5508 Controller

I'd like to replace my 4402 Wireless controller with a new 5508. I have migrated the exact configuration from my 4404 controller to the 5508 and they are both running the same version of code. I'm worried that if I replace the 4402 with the 5508 controller, the Access Points will not rejoin to the new controller or they will join but will have lost their configuration e.g. AP Name/location etc etc. AP models registered to the existing controller are 1131, 1142 and 3502. I am also using Cisco WCS.
 
As long as the new controller has the exact same configuration, is it possible to replace the 4404 with the 5508? Will the existing Access Points join the new controller? Is there any other configuration required? I have read about doing this using mobility groups however would rather not if possible.
