Hi Marcus,
I believe you can only re-host adder licenses and not base licenses (might want to confirm with Cisco). For example, you may have an AIR-CT5508-50-K9 which has a 50 base license and then have 150 adders (in various increments). I think in that scenario you would only be able to re-host the 150.
Additionally, I believe you need to have purchased support from Cisco TAC in order to transfer but I could be wrong!
Cheers
Ric
