Zypper and Wagon are documented supported methods for upgrading OES 11 SP1 to OES 11 SP2.

I'm curious about another upgrade method via the Updater Applet.

When I login to the OES 11 desktop, the Updater Applet informs me that a Channel Upgrade is available for OES 11 SP2.

The Updater Applet has an option to perform the upgrade from OES 11 SP1 to OES 11 SP2.

This upgrade method seems to work great.

Was this upgrade method an option that was introduced after the documentation that's available for upgrading to OES 11 SP2?
