I am looking to upgrade my SLES11 servers to SLES12 SP2 and would like to keep my OES servers at the same major revision for the OS. I am retiring from my jobs in a year and wanted to get all my servers to the latest version so my predecessor has the longest window until worrying about EOL support. OES2015 SP2 is supposed to be based on SLES12 - does anyone have a crystal ball on when that may be available?

My recourse will be to do an in-place upgrade of the OES servers to OES2015 SP1 and SLES11 SP4 and leave it to whoever follows me to migrate to the latest versions.
