SLES 12 SP3 to SP4: In-place upgrades on Azure

Again the SLES team made this really easy – using zypper and the online update repositories. Less than 15 minutes per server – and a single reboot.

Documentation is at https://www.suse.com/documentation/sles-12/book_sle_deployment/data/sec_update_migr_zypper_onlinemigr.html

Accept the recommended upgrade – and read and accept the EULA – and you’re away. For me 240MB download, 156 packages, 10 minutes of install, one reboot.
