RE: NEWBIE -- needs help in moving directories from one repositor y to another

[Luna, Glen]

Rob,

Thanks for the reply. 

Yes, I do want to capture the version history. The source repository
is on a vendor's (for simplicity I'll call it Bob) host. In one of 
Bob's root directories, there is our code (in subdirs) and there 
is the Bob's code (in a couple of other subdirs). The coupling of our 
code with the Bob's code has resulted in a product used by several 
customers. We've maintained our code, under CVS, on Bob's host for at
least five years and have a good working relationship. Bob's code is
essentially COTS to us. Bob farms out his code to other clients.

Up until last year our code development was maintained under a single 
CVS repository - Bob's. Now, our group is producing other products. 
And the code for these products are being maintained in CVS 
repositories on our own hosts. We now want to move our code from
Bob's machine and onto our own. Again, his code and ours are in the 
same root directory but in different subdirs.

That's the core of my impending task.

I don't know if the UIDs are the same. I'll have to ask the systems 
folks. I'm betting that they are not. If they aren't, what problems
could I face? What should I keep an eye on?

Hmm.. so you just want to move the files, and lose all version
history? I would just tar up the original root and extract it on
the target machine, then remove the extraneous subdirectories from
the target machine.

This would also preserve permissions and UIDs, and should be
smooth assuming that the UIDs on both servers match.

My apologies if I am misunderstanding something :)
Please describe further what it is you want to do.
