I have just inherited a Subversion server that is a mess. I want to migrate to a new server with a saner file system layout. I figured a svnadmin dump and then svnadmin load for each repository would be sufficient. However, I have learned the repositories make use of svn externals, and mostly absolute externals. Is it possible to move repositories with externals to a new server?

My current configuration:


The configuration I want to move to:


Disclaimer: I've never tried this.

Externals are just properties, and I'm pretty sure those are dumped as plain text. Could you try passing your dump file through a perl(or whatever you're comfortable with) script to modify the properties to the new url?

  • worth a shot. If it fails you just get to write a perl script that finds all the externals properties in the tree and does all the substitutions. Then commit them. – pjz Aug 7 '10 at 3:09

  • Just a note, I ended up not doing this at all. Turns out you have to modify checksums when the dump file is being created. It just wasn't worth the effort. – James Sumners Sep 24 '10 at 18:12
