You drop the vendor branch download on top of a copy of the old
branch, using something like this:

    svn copy svn://repo/tags//vendor-1.0 svn://repo/branches/vendor-2.0-merge
    scn co svn://repo/branches/vendor/2.0-merge 2.0-merge

    tar xzvf vendor-2.0.tar.gz
    rsync -avH --exclude=.svn --delete vendor.2.0/ 2.0-merge/
    cd 2.0
    svn status
    [ Add necessary files, delete missing files, set whatever svn
properties you need, etc. etc.

    svn commit
    svn copy. svn://repo/tags/vendor-2.0

Delete svn://repo/branches/vendor-2.0-merge if you feel so inclined.

This will combine the forced upgrade into a single commit. Don't do
*ANY* other work in those branches and tags.

You can then try to merge that tag with your trunk or other branches,
although SVN merges are not their strongest feature.
