When trying to upgrade a PC from SLES12 SP5 to SLES15 SP6, the upgrade just stopped after 400 packets or so (with over 1200 packets to be done). When trying a new installation instead (the PC being unusable), I need the registration key that I did not write down, but I had made a backup.

So the question is: Is there some file on the local system (so that I can restore it from backup) telling me what the SLES registration code is?

You can view the registration key at SUSE Customer Center: https://scc.suse.com/home .

To see your "Registration code", you login into SCC, click your organization under "MY ORGANIZATIONS" on the left side, then select "Subscriptions" top mid, then select the correct subscription (example: "SUSE Linux Enterprise Server..."), then you can find the registration code in red color under tab "Subscription Information". Make sure your subscription is not expired. (You also can show expired subscriptions.)

To see your "Mirroring credentials", you login into SCC, click your organization under "MY ORGANIZATIONS" on the left side, then select "Users" top mid, then select "Organization Credentials". Those can be used for SMT, RMT and SUSE Manager.

If you want to register a usual system, just open yast via console and select "Software", then "Product Registration" and choose registration via email. You need to use the same email as of your SUSE SCC account.

Alternatively, you may find the "key" files in directory /etc/zypp/credentials.d/, they can be opened using a text editor - but these seem to be encrypted.

I've not tested it, but if you want to "transplant" the old key files to a new system, you need first to use the same OS version and then copy following files from the old to the new system:

/etc/SUSEConnect
/etc/zypp/credentials.d/*
/etc/zypp/repos.d/*
/etc/zypp/services.d/*
/etc/machine-id

Maybe /etc/machine-id is not needed.

A problem could be, that your old system might have contacted the registration server - while setup - and told it to change the registered OS version to the newer one. If so, the old registration won't work anymore. Usually you need to register it new. But then you need to login into SUSE Customer Center anyway and delete the wrongly registered system.
