Let me get this straigh: You have several version control systems, and
you want to migrate them all to CVS because that's what you company
has standardized on.
I wish I could help you, but I've been in this business for a long
time, and I know of no tool that migrates from Subversion to CVS.
There are a lot of tools that allow you to go from CVS to Subversion,
but I don't know any that do it the other way around.
Try march-hare.com. They're a consulting firm that specializes in CVS.
That said, CVS itself is not currently being maintained or developed.
March-Hare is working on CVSNT which is now evolving a bit away from
CVS itself and is more concentrating on Windows based systems.
Basically, I personally would be hesitant to start a new project using
CVS. There are simply better version control systems (and I am not
simply talking about Subversion) that are in active development and
are being actively supported.

Is there something you don't like about Subversion?
This seems rather strange because Subversion was designed to be very
similar in workflow and command structure to CVS. I could understand
if you wanted to move to Git or ClearCase since these two tools are
very different from both CVS and Subversion and many people feel that
the way CVS and Subversion work don't match what they want to do.
However, Subversion is very similar to CVS, but has some very nice
features that CVS never had:
* Directory mapping. CVS cannot map when files move from one directory
to another. Subversion does.
* Change Set. In CVS, if a user makes a set of changes, backing out
that change is very difficult because each file change is a separate
transaction. In Subversion all changes are in a single change set, so
it's very easy to backout a user's change.
* Speed: Tagging and branching in CVS is very time consuming. It use
to take us 45 minutes to tag a release, and we were doing this after
every build, so we could easily track the files in that build. In
Subversion, a tag takes a fraction of a second. This is important in a
continuous build project.
* Merging. CVS does absolutely no merge tracking. You have to track
all of your changes when you merge from branch to branch. Subversion
tracks merging. It's not the best at merge tracking, but it's way
better than CVS.
* History tracking: CVS history takes forever to generate, and each
file has its own history, to go back in time and see what was changing
on a project involves writing your own script and usually about 20 to
40 minutes of run time as CVS goes through each file in the project.
Subversion can give you a history almost immediately.
* Tags and Branches: Find all the tags and branches in your project.
In Subversion, it's a single command. In CVS, it's getting a complete
history of each file and a bunch of parsing.
However, maybe there is some reason you feel that CVS is better at
than Subversion, and it is worth going back to CVS to get this
particular feature. We'd be interested in your reason.

You're going backwards in time! We developed Subversion to fix many of the
issues in CVS, so I don't recommend going back to CVS.
Here's a good document on describing the changes in Subversion for CVS users:

Boy, not a very convincing argument in that document. Not one I would use to
have somebody not go back to CVS :) I'm sure Google could have found a few
better ones. Gotta love the "Still not know how good are some decisions they
make" one :).
About the only one that has merit is the "Tags & Branches (!!! IMPORTANT)" one.

Blair

If I understand correctly, your company is moving to svn, but you (personally) want to move from svn to CVS?
I would recommend you use SVN too, it is a very good tool, allegedly better than CVS in every way, or at least, every way that matters. Take a look at http://www.pushok.com/soft_svn_vscvs.php for a very old comparison between the two, things have moved forward for SVN since then, and it has many, many, many excellent features that CVS doesn’t have.
If you absolutely must still have CVS access, you can set a post-commit hook to transfer every file written to SVN back to a CVS repository. You’d be silly to do it, but it can be done: http://sam.zoy.org/writings/programming/svn2cvs.html
