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”.
Some Background: All SP3 Systems have the sle-11-sp3 basechannel with different custom channels and can be managed as salt-minions. And YES, I’ve already read the documentation & Releasenotes to get some migration information.
My current approach is:
Install the Migration package in SLE11SP3
Manual mount the SLE11-SP4-Pool/Update from our old SMT-Server
run "zypper dup --from [SLE11-Rpos]
switching the basechannel on SuSE Manager to SLE11-SP4 for the system & zypper up -t patch
But this seems to be very hard way.
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?
which SUSE Manager version is this, do you have current patches applied to it, are you already connecting to SCC?

looking at it from a “let’s do it without SUSE Manager” point of view, like your current approach does, I see significant deviations from the SUSE-documented steps (i.e. https://www.suse.com/support/kb/doc/?id=7016711, “2) Update by using zypper”):
update the SLES11SP3 system to latest code level (why SMT? Doesn’t your SUSE Manager provide the required channels?) (zypper ref -s; zypper --non-interactive patch --auto-agree-with-licenses --with-interactive; zypper --non-interactive patch --auto-agree-with-licenses --with-interactive")
install applicable product migration packages
switch the system to the SLES11SP4 channels via SUSE Manager
refresh the repositories, disable any possibly still enabled SP3 repositories, enable any possibly not enabled SP4 channels
“zypper dup …” per above article
But of course, your usage of the “old SMT server” may be related to the state of the SLES11SP3 channels in your SUSE Manager.
But this seems to be very hard way.
I agree to some extend - but at least it’s a scriptable way, if you’re using a mechanism that lets you synchronize installing the SP3 migration packages, switching channels and then running appropriate “zypper dup” per server.
We have about 300 SLES11SP3 Systems to migrate and I look for a good automated way over SuSE Manager.
From my personal point of view, automating that update needs to take into account the servers’ inter-dependencies and does have a great potential for running havoc, if not prepared to handle upgrade failures. Of course, initiating the SUSE Manager “SP Migration” should be available via some automated way, but usually not “all at once”
And of course you’re right to expect SP migration to work within SUSE Manager, maybe that’s something to tackle first?
