One of our old faithful deployment machines at work got reinstalled and we upgraded SVN from version 1.4.3 to 1.4.6

However the data was incompatible, so we had to run the following commands in order:-

for every folder:-

Take a dump of that path and redirect the output to a temporary path and preserve the relative heirarchy.
Delete the Files under the Path
ReCreate the following frompath which just got deleted
Load this frompath with data from the temporary File Path

And thats it. It can all be done using svncopy.py Since I dont have an online CVS or SVN account, I’ll paste the code here.

I recommend you to look at the code and comment out the lines that you want to comment out. I bear no responsiblity in case anything goes wrong. Please backup the folder if you fear data loss.
