I'd like to add that since Subversion 1.5 you can use relative locations for svn:externals properties as documented at [1], in case that's helpful.

No you cannot do it in the way you described, and your approach is incorrect. Not for svn, but IT. For subversion: If you alter the history of the repository in any way, all working copies will be invalidated. So even if you repeat the steps described, you will need to get new working copies. Please separate immutable history from the location-specific configuration. Either have the network configuration represented in a location-specific source, such as local DNS or other network-discoverable data. Or simply do not version location-specific data that creates a need to change it. Or make the code discover it's own location and pick one of the versioned configurations. This isn't even working around a limitation of svn, but good system design. If you proceed like that, you can use the incremental dump feature which should make administration faster and more straightforward. Andreas
Maintaining a SVN 1.7 mirror without network access
I have a Subversion 1.7 repo. I need to periodically mirror it to a location that does not have direct net access (I can transfer a .dump file to it). One catch is that the mirror needs to be able to receive one divergent commit after the load (this commit alters svn:externals locations to be appropriate for the mirror's network). I'm fine with manually reapplying this commit after each load. Currently, when I want to refresh the mirror, I have a sysadmin log in to the mirror SVN server, delete and recreate the repo from scratch, and then load the dump into it and apply the single manual commit. This works, but is pretty cumbersome, and requires an admin. Is there a way to replace the mirror repo with the contents of the dump, without needing to manually delete it first - and ideally without needing local rights (perhaps using svnrdump)? Essentially, I want the revisions from the dump file to replace the same-number revisions in the repo, rather than appending. Is this possible? Thanks!
