[QUOTE]Procedure for upgrading from SLES 10 / SLED 10 (GA version, Service Pack 1, Service Pack 2, and Service Pack 3)
There is no supported direct migration path to SLES/SLED 11 SP2. An update has to be performed from SLES/SLED 10 GA to SP 1, then to SP 2, further to SP 3, and then to SP4 by using the respective boot media.[/QUOTE]
Interestingly, the “upgrade to SLES11SP1” article (http://www.novell.com/support/kb/doc.php?id=7005410) doesn’t list the requirement to go to SLES10SP4 first.
I have no experience with GW, so I cannot tell how much hassle it is to configure a fresh SLES11 install to fulfill your requirements.
