Subversion repo upgrade makes repository unusable

Question

I recently upgraded my subversion server from 1.4.6 to 1.6.11. The repos all seem to work correctly after this. I then try to upgrade a repo by issuing the svnadmin update command, and it produces no errors and says the update is complete. However, I am unable to open the repository after this. I get the following error when trying to open the repo: Could not open the requested SVN filesystem.

I am using Apache, not SVNServe. Any help would be appreciated!

Have you also upgraded your Subversion client to a corresponding compatible version? The client may not be able to understand the newest server filesystem format.
