So the problem is that the CC-By-SA-1.0 does not have the
license upgrade clause?

Sounds like you'll need to either scrub the 1.0 content out
of the wiki or get original sources to upgrade the license.

Alternatively, you could use a blanket license statement for
the site which says that content is under the By-SA 2.5 "unless
otherwise noted", and then put "By-SA 1.0" notices on the
affected pages.
