This has pretty little to do with TSVN, since TSVN is rather an SVN client.
The server typically runs a vanilla SVN installation. Therefore, this is
better asked on the SVN mailing list.

However, let me ask you a question: If you don't know how to do that, how
would you ever recover your repository after e.g. a fatal hardware failure?
Seriously, this recovery process is part of your backup strategy and you
absolutely must test it. SVN is not a backup tool that magically preserves
your data when the server goes up in flames.

In order to move a repository, you would normally use 'svnadmin' to dump and
load it. All that is documented, just look for 'svnadmin', 'dump' and 'load',
that will get you started.

Wait: Firstly, you can have multiple repositories on one server, so it might
be easiest to do just that and keep the separate projects in separate
repositories.

If you really want to merge repositories including their history, you need to
dump/load them, using svndumpfilter on the intermediate dump files. Do a
websearch on this, the problem isn't new and the various solutions aren't
either.

Typically, you can check out as many working copies from a repository as you
want. Those are considered scrap space to work on and then throw away when
not needed any longer. I guess you either mean directories inside the
repository or maybe something different. Please reread the documentation, the
term "working copy" is defined there, so that you don't confuse it with
anything else.

"keep track of revisions separately" - what does that mean? Do you mean that
you want the revision numbers used by SVN internally to be separate? In that
case, again, read the documentation (I believe that even is an FAQ entry). In
short, it isn't possible.

BTW: You will need the "svn relocate --switch" command to reuse existing
working copies when moving repositories.
