This is a surprising remark for me, as the docs (and also SUSE engineers I spoke to at SUSECon) mention SLES 11 SP3 to SLES 12 IS supported.

From the docs:

"SUSE Linux Enterprise (SLE) allows to update an existing system to the new version, for example, going from SLE 11 SP3 to SLE 12. No new installation is needed. Existing data, such as home and data directories and system configuration, is kept intact. You can update from a local CD or DVD drive or from a central network installation source. "


" Supported Upgrade Paths for SLE

SUSE Linux Enterprise supports direct upgrades from one release to the next. For example, if you currently run SUSE Linux Enterprise 11 SP2, you will upgrade in two steps, first to SUSE Linux Enterprise 11 SP3 and then to SUSE Linux Enterprise 12. "

The original location of those quotes :

Has something changed in regards to the 11SP3 tot 12 upgrade?
