I have a sles12 system registered on our local smt-server. Now we want move it to SuSE manager.

- System is already registered on SuSE Manager via bootstrap script
- edited the file "/etc/SUSEConnect" manually and directed it to suse manager (system is direct connected without proxy)
- when trying to make "zypper migration" for update to sles12 sp3 it leads to the message
"Your Registration Proxy server doesn't support this function. Please update it and try again."
