Thanks for all the input.

After reviewing the information and stepping back to get our
heads together, what we are going to is "tar" up the vendors
repository and install the root that we want on our own 
repository. That root will be a new root on our repository. 
I foresee no conflicts there. And it is just a single root
that we want. No worries (I hope).

But we'll also be pulling over the CVSROOT root 
directory. Of course we have an existing CVSROOT root
in our repository. I did notice that the only files that 
seem to change is the val-tags and the history files. 

Will I have to merge these files or does it matter if I 
just keep things as they are in our CVSROOT? How important
are these two files?

Yes...I do want to retain version history.

Thanks in advance.

The simplest thing to do, then, is to copy the relevant files and
directories directly from the repository on host_1 into the repository
on host_2 using whatever OS-level commands you're comfortable with (tar,
cpio, backup, scp, rcp, ftp, whatever).  There's no magic in the
repository -- the file and directory structure is all there is -- so
using OS commands preserves all the revision history and is easy. 
Rearranging repositories like this is not something CVS was designed to
do, so there aren't any CVS commands to do it.

You'll have to do two checkouts, one for each host.  You can do the
second checkout inside the working directory from the first checkout,
however, and from that point on you can treat it as a single tree --
things like update and commit will automatically go to both
repositories as needed.
