I foolishly just moved a Subversion repository by importing the contents of a current checkout into a new repository. Wrong. A friend pointed out these instructions that make it easy and preserve the revision history.
Here’s the trick:
svnadmin dump /path/to/repository > repository-name.dmp
and
svnadmin load repository-name < repository-name.dmp
