Transfers from one repository to another

["Adams, Arthur (Aquilent)" <Ar...@va.gov>]

We are considering migrating the project I work on from multiple
SubVersion repositories to one unified repository. 

We'd like to see that our files keep their svn history in the new
repository, but, as far as I can tell, that's not possible. (By
"history", I mean both the checkin comments and the diffs. In other
words, I want to have everything I had in the old individual
repositories in the new unified one.)

I've looked at svnsync, but that seems to be designed to mirror a one
repository in another. It doesn't seem to allow copying multiple
repositories into one.

My research seems to indicate this isn't possible. Is there a way to do
this?

Failing that, if we wanted to move to a unified repository, what would
be the best way? My thought is to keep the old ones around, with write
permissions locked down tight, so we can go there to access the history,
at least.

And of course you will have to be careful with legacy log comments à la
"merged rev 1234 - 1239 of branches/path/ to the trunk" since the
projects in the new *big* repo will share their revision numbers.

You can 'svnadmin dump' the contents of each of the repositories.
Then, you can load each of the dumps into one newly created
repository. You'll have all projects in the same repository; you'll be
interested in the --parent-path option of 'svnadmin load'.

HTH,


Erik.

It is possible. As Erik said, you can svnadmin dump each repository,
then filter the dump with svndumpfilter to just contain your project
(unless you are merging the entire repositories). The disadvantage is
that your revision numbers will be out of order date-wise, which could
make things confusing. One solution is to use svndumptool, which is not
part of the SVN distribution.

http://svn.borg.ch/svndumptool/

You can use the merge command to intermix the revision numbers so that
they are ordered by date. Otherwise, with the standard dump, dump, load
method, you'll get all of repository A's revisions then all of
repository B's.
