“Additionally, although all history and dates are preserved in the revisions, the big repository has commits that are not in chronological order since the import was processed by repository.”

Have you found a way to fix this? I makes running an svn cat at a particular date for a specific file on a folder imported later in process impossible. svn looks for the “earliest” revision number for that date and finds one for an earlier import process, i.e. before the folder we care about existed, and fails.

The tricky part is that an “svnadmin dump” command dumps everything, by revision, not by path. To filter by just a particular directory, you must filter the dump file by directory. For this, use the “svndumpfilter” command.

The post Using piped svndumpfilter commands to separate an svn repository touches on this, albeit written for Linux.

I hope this gets you started… I’ll try to write up a sample script for accomplishing this in the next week. I’ve been needing something inspiring to blog about. Stay tuned.
