How do subversion clients deal with a historic change in a repository?

Question

I had to make a change to a subversion repository database. I created a dump, filtered out a revision and created a new database.

This new repository of course shares a lot of content with the working copies clients of the old repo already checked out, however, it is missing a revision inbetween.

The revision that was removed did not add any data, it only changed some files.

Is it possible to simply replace the old server database with the new one without causing havoc on existing clients working copies? Or do I have to have all clients check out a fresh copy of the new repo instead?

More generally, how do subversion clients deal with a change in structure on the server side? I'm primarily interested in TortoiseSVN.
