Going from SLES12 SP2 to SLES12 SP3, online

SLES 12 SP3 was released some time ago and as we have customers running on that I thought it might be a good idea to test the upgrade from SP2 to SP3. Actually it turned out this is quite easy and can be done online. The supported methods for doing this is either by using YaST or Zypper directly. As I wanted to stay on the command line I’ll use Zypper for the scope of this post. Lets go…

As said above I’ll be upgrading from SLES 12 SP2:

postgres@sles12sp2:/home/postgres/ [pg963] cat /etc/os-release 
NAME="SLES"
VERSION="12-SP2"
VERSION_ID="12.2"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP2"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:12:sp2"

When you have another setup make sure that the upgrade path is supported, which you can check here.

My current kernel version is:

postgres@sles12sp2:/home/postgres/ [pg963] uname -a
Linux sles12sp2 4.4.74-92.38-default #1 SMP Tue Sep 12 19:43:46 UTC 2017 (545c055) x86_64 x86_64 x86_64 GNU/Linux

The first thing you should do is to apply the latest patches:

postgres@sles12sp2:/home/postgres/ [pg963] sudo zypper patch

As I am fine with the summary I’ll proceed:

(Use arrows or pgUp/pgDown keys to scroll the text by lines or pages.)

In order to install 'SUSE Linux Enterprise Software Development Kit 12 SP3' (product), you must agree to terms of the following license agreement:

SUSE(R) Linux Enterprise Software Development Kit 12 Service Pack 3
 
SUSE End User License Agreement 

Of course you need to agree to the license agreement and then the migration starts. At the end you should see something like this:

    dracut: *** Creating image file '/boot/initrd-4.4.82-6.9-default' ***
    dracut: *** Creating initramfs image file '/boot/initrd-4.4.82-6.9-default' done ***

There are some running programs that might use files deleted by recent upgrade. You may wish to check and restart some of them. Run 'zypper ps -s' to list these programs.

Executing 'snapper create --type post --pre-number 29 --cleanup-algorithm=number --print-number --userdata important=yes --description 'after online migration''

That’s all:

PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:12:sp3"

Of course the kernel is still the old one and the new one will become active after the next reboot:

postgres@sles12sp2:/home/postgres/ [pg963] sudo systemctl reboot
...
...
postgres@sles12sp2:/home/postgres/ [pg963] uname -a

Quite easy.

    Hey,

    thanks for sharing your experience. One thing I wanted to point out and what confuses me right now is the output while actuelly upgrading from SP2 to SP3 (line 112-114) which is saying:

    “[…] The following 19 packages are going to be downgraded: […]”

    This message is also shown on my system when trying to upgrade – except for a slightly different list of packages. This seems a little bit unusual for a migration from SP2 to SP3, don’t you feel the same? Maybe you have any thoughts on that?

    Regards,
    Daniel

      Hi Daniel,

      my guess is that these packages in the SP2 installation are newer than what you will get when you migrate to the base SP3 without any updates. But I’d need to verify this. Thanks for pointing that out.

      Cheers,
      Daniel
