I'm investigating migrating a source code repository currently kept under SCCS on an aging Digital UNIX box to Subversion on a Windows box. My initial searching has led me to a python script, sccs2svn, which looks like it would do the job - with some restrictions. A du -sk on the SCCS directory shows it to be about 550MB in size.
From what I can tell, the script runs on a local machine and operates on both SCCS and SVN locally: SCCS through executing SCCS commands directly; SVN through a python module, but also calls svnadmin to create a local directory.
Unfortunately, I need to create the repo on a different server; from what I read in the SVN mailing lists etc, a SVN repo can't simply be copied between servers if the platform is different: an svnadmin dump and restore is required.
The only way I think I can see this working is as a two-stage migration: firstly, to install SVN and python on the existing server, run the script there, then secondly dump the repo out and load it into the Windows SVN - which should work, just slightly more time consuming and requiring a little more disk.
Is anyone aware of a way I could do this without doing it in two stages? Could the python script be modified to act upon a remote repository if the lines to create the repo are commented out? I'll be doing some reading into the Python SVN module, but Python isn't a scripting language I've played with before.
