Anyone upgrade an existing gw2012sp2 server from sles10sp4 (oes2sp3) 64
bit to sles11sp2 (oes11sp1)?

I have a few servers, most running POA's, but one has a POA and MTA
that I'd like to do this on, but wanted to get some feedback first.

Big reason being I tried an upgrade of a file server from sles10sp4
(oes2sp3) to sles11sp1 (oes11) a little over a year ago, and it blew up
in my face. Ended up having to build the server over, being VERY
fortunate the nss data and file rights were still intact.
