SDB:How to migrate to SLE

This topic is getting more interesting with Closing The Leap Gap when openSUSE Leap 15.3 and newer will be newly based on binary rpms from SUSE Linux Enterprise Server 15.

The following is the current abstract procedure to migrate from openSUSE Leap 15.3 to SUSE Linux Enterprise Server 15 Service Pack 3:

1. You will need to install SUSEConnect and yast2-registration.
2. Register your system with a valid SUSE Linux Enterprise Server 15 Service Pack 3 Beta registration code.
3. Run yast2 migration to migrate your system and reboot.
4. If something fails or you want to try the procedure again use snapper rollback to restore changes on filesystem.

Emergency Rollback

We recommend to use btrfs based installation and snapper openSUSE:Snapper_Tutorial for effortless rollback. Installing rollback-helper will help you to cleanup SCC in case that you'd like to revert filesystem changes and the entire registration process.

Migration from openSUSE Leap to SUSE Linux Enterprise Server

This section will cover a standard openSUSE Leap to SUSE Linux Enterprise Server migration.

It's updated to match required steps to migrate openSUSE Leap 15.3 Beta to SUSE Linux Enterprise Server 15 SP3 Public Beta.

What about older Releases? You can follow the same steps to migrate Leap 15.2 to SUSE Linux Enterprise 15 SP2, but all of rpms will have to be replaced and that will take significantly longer. Additionally you'll have to allow vendor change for rpms (openSUSE -> SUSE LLC). The last step is no longer required in migration from Leap 15.3 to SLES 15 SP3.

200px	Install tools for registration (30 seconds) In this section we will install yast2-registration which also installs required SUSEConnect. rollback-helper is only needed in case that migration would not work as expected and you'd like to use snapper rollback to revert filesystem changes and cleanup the SUSE Customer Center registration. Please note that yast automatically creates snapshot prior both registration and migration. Open terminal and execute: $ sudo zypper in yast2-registration rollback-helper # to enable the rollback service $ sudo systemctl enable rollback
200px	Register your system (30 seconds) You'll need a valid SCC login and a registration code for this step. You should request on from https://suse.com/betaprogram/sle-beta/#faq-reg # This will ask for a valid SUSE Linux Enterprise Server Registration code $ sudo yast2 registration
200px	The migration (2 minutes for repo refresh) We recommend using yast2 instead of zypper migration, because our openQA test suite uses yast2. This part might ask you to resolve conflicts, in case you have some on your system, e.g. that you use 3rd party repos, or e.g. devel repositories from OBS. $ sudo yast2 migration
	Reboot to SUSE Linux Enterprise Server Reboot to SUSE Linux Enterprise Server. # And we're done sudo reboot
	Need to rollback? Something didn't went too well? Or perhaps you've changed your mind and would like to get system to the state before migration or registration? It's quite easy. sudo snapper list # selected revision prior to migration or registration sudo snapper rollback $REV sudo reboot # and that's all Known issues
