RE: CVS to Subversion Migration

Couldn't one use pre- or post-commit hooks to remove the cvs2svn:rev-num property whenever someone commits a change? That way, all files which were unchanged after migration keep their rev-num property, and all files which are changed afterwards have it removed. This hook would have to be enabled right after the migration though.

Haven't thought a lot about branching and merging, but I guess that should be ok as well (as soon as you commit any change, the rev-num property is removed from all changed files).

Regards,
Johan

Just echoing the sentiment.

cvs2svn worked well. We did a project at a time. Just a word of
caution. Be careful with the --cvs-revnums flag. I used it and thought
it worked great. It put a cvs2svn:rev-num property on each file
version with the CVS version of that file. I figure this would come in
handy if a developer wanted to know exactly what revision a file was
in CVS.

Then, to my horror, I suddenly realized that it was putting this
property on all subsequent revisions of the file. I had to checkout
the entire source repository, remove this property, and then commit it
back again.

Merging and branching kept bringing this property back and it
generally made a mess of things for a few months. In the end, it
really didn't do anything for us. No one was really interested in the
CVS revision number anyway.

If you do use it, you must check everything out, remove the property,
and then recommit once the conversion is done.
