what is the best practice for migrate an SLES11SP3 system to SP4? The system is registered at SuSE Manager and when I choose "SP-Migration" on the UI it results into the error "No available migrations found".

We have about 300 SLES11SP3 Systems to migrate and I look for a good automated way over SuSE Manager.

Any similar problems in your environment? Who have the brilliant idea or hint for me?

Thanks in advance
