Service Pack Migration
SUSE Manager uses SUSE Linux Enterprise Server 12 as its underlying operating system. Therefore Service Pack migration (for example, from version 12 SP1 to 12 SP3) may be performed in the same way as a typical SLES migration.
Upgrading PostgreSQL to Version 9.6 Before Migrating to SLES12 SP3 or Later
Before migrating the underlying system to SUSE Linux Enterprise 12 SP3 or later, you must upgrade PostgreSQL to version 9.6.
The migration needs PostgreSQL 9.4 and 9.6 installed in parallel and PostgreSQL 9.4 is only available in SUSE Linux Enterprise 12 SP2. For more information, see <<bp.sect.postgresql.prepare.upgrade>>.
SUSE offers a graphical and command line tool for upgrading to a new service pack. Comprehensive documentation for executing service pack migration scenarios is located in the SUSE Linux Enterprise Server documentation chapter https://www.suse.com/documentation/sles-12/book_sle_deployment/data/cha_update_sle.html.
