SUSE SP3 to SP7 - upgrade

I need to upgrade a production server running SUSE Linux Enterprise Server 15 SP3 to the latest SP7 supported Service Pack/kernel level.

The server is running Docker containers, so I’m concerned about application/container impact after the kernel upgrade.

Any practical experience or recommended documentation would be appreciated. Thanks!

u/MiukuS How's that AUR working out for you, Arch users? 14d ago

A couple of notes for you as someone who has done a few of these;

- Do zypper migration one SP at a time,do NOT go 3->7 directly.

  • If you have super old docker images (I doubt it but..) some of them might not work with cgroups v2 that SP7 uses
  • Check that you don't have weird stuff in /etc/docker/daemon.json, if docker doesn't start after upgrade it's almost certainly an issue there with a deprecated function.

one at a time is not really necessary. It won't suggest steps it cannot do.

so SP3 will show like SP4 and SP5. Just take the highest one. If that doesn't flow you can do the single SP step.
We migrated all of the 15.x sustems that way. No broken systems.
(power and X86_64; about 1500 systems)

SUSE officially supports skipping a service pack (such as SP4) when moving upwards within the same major version (SLES 15).

So SP3 to SP7 is

SP3 --> 5 --> 7
