I currently have a few servers running SLES11 SP3 and want to upgrade them to SLES12 SP2 via installation media. The SLES12 SP2 documentation talks about the upgrade from earlier versions to SLES12 SP1. Can I do a straight upgrade from SLES11 SP3 directly to SLES12 SP2 or do I need to first upgrade to SLES12 SP1 and then follow the documentation to upgrade SLES12 SP1 to SLES12 SP2?
