One really good feature from SUSE Linux Enterprise (SLE) is that it allows you to upgrade from your running system to a new service pack online.
\nLet’s say from SLE 12 SP3 to SLE 12 SP4. No new installation is needed. All existing data are kept intact.
\nIn the following blog post, I will show you how easy it is.
\n<\/p>\n
Of course, before upgrading we need to do some checks to be sure the system is properly prepared.
\nWe first start with the version.<\/p>\n
SUSE12SP3:~ # cat \/etc\/os-release\nNAME=\"SLES\"\nVERSION=\"12-SP3\"\nVERSION_ID=\"12.3\"\nPRETTY_NAME=\"SUSE Linux Enterprise Server 12 SP3\"\nID=\"sles\"\nANSI_COLOR=\"0;32\"\nCPE_NAME=\"cpe:\/o:suse:sles:12:sp3\"<\/pre>\nThen the current system must absolutely be updated to the latest patch level, otherwise it won’t be supported.<\/p>\n
SUSE12SP3:~ # zypper patch\nRefreshing service 'SUSE_Linux_Enterprise_Server_12_SP3_x86_64'.\nRefreshing service 'SUSE_Linux_Enterprise_Software_Development_Kit_12_SP3_x86_64'.\nLoading repository data...\nReading installed packages...\nResolving package dependencies...\nNothing to do.<\/pre>\nBackups<\/h2>\n
For safety reasons and in case we should rollback, we back up all used repositories and also all installed packages as following<\/p>\n
SUSE12SP3:~ # zypper lr -e repositories.bak\nRepositories have been successfully exported to .\/repositories.bak.repo\nSUSE12SP3:~ # rpm -qa --queryformat '%{NAME}n' > installed-software.bak<\/pre>\nMigration plugin<\/h2>\n
As a prerequite and as we will perform from the command line, we need to know if the Zypper subcommand for online migration to new service pack is installed<\/p>\n
SUSE12SP3:~ # zypper se zypper-migration-plugin\nRefreshing service 'SUSE_Linux_Enterprise_Server_12_SP3_x86_64'.\nRefreshing service 'SUSE_Linux_Enterprise_Software_Development_Kit_12_SP3_x86_64'.\nLoading repository data...\nReading installed packages...\n\nS | Name | Summary | Type\n--+-------------------------+----------------------------------------+--------\ni | zypper-migration-plugin | Zypper subcommand for online migration | package<\/pre>\nAs it is already installed we can carry on.<\/p>\n
Migration<\/h2>\n
Everything is in place, we can start the upgrade process<\/p>\n
