how to upgrade 11.0 > 11.1

Hello,
I have here a few openSuse 11.0 virtuallized servers, running under the xen hypervisor. How can I do the upgrade to the released 11.1? Can I just go to Yast, Software Repositories and change the urls to 11.1, i.e.
Index of /distribution/11.0/repo/oss
to
Index of /distribution/11.1/repo/oss
and so on?

I just tryed it with one and after changing all items to 11.1, I still don’t have any updates. Is it correct?

After changing it should see all updated packages. You just need to update the cache. run in terminal as root “zypper up” then check updates.
