Merging repositories is easy. You "svnadmin dump" both old
repositories, then "svnadmin create" a new repository, then "svnadmin
load" both dumpfiles into the new repository.

Note that your revisions will now not be in chronological order. The
only side-effect of this is that the -r {DATE} feature will not work.
If you want -r {DATE} to work, then you can use the repomerge.py
script to load the two dumpfiles with revisions interleaved to
preserve chronological order:

http://svn.haxx.se/users/archive-2006-01/1168.shtml

Whichever way you choose, you will need to throw out all existing
working copies from the old repositories and check out new working
copies from the new repository once you're done loading.

The revision numbers in the new repository will now likely not be the
same as the revision numbers in the old repositories, especially if
you interleaved the revisions using repomerge.py. If you ever had any
comments in your log messages that referenced specific revision
numbers, these will no longer be accurate.
