Tumbleweed > 13.2

How does one move from Tumbleweed to 13.2?

Change the repositories to point to 13.2 oss/non-oss/update and zypper ref && zypper dup.

For example on my 13.1 boxes when I do a manual update I just; sed -i ‘s/13.1/13.2/’ /etc/zypp/repos.d/* && zypper ref && zypper dup

The same as to any other version I’d say:
Remove the Tumbleweed repo(s), add the 13.2 repos, run “zypper dup”, and pray.

Or boot from an installation medium and choose “Upgrade”, should work as well.

But please post your repo list.

zypper lr -d

If you still use the “old” Tumbleweed (openSUSE-Current repos + an addon Tumbleweed repo), you should be on 13.2 already (or the next “zypper dup” will bring you to 13.2).
As with every other openSUSE release, that Tumbleweed addon repo has been emptied, and openSUSE-Current moved to the latest version.
In this case, just remove the Tumbleweed repo, and maybe change the xxx-Current repo URLs to point to 13.2 instead, so that you’ll not be upgraded to 13.3 automatically once it is released.
