RE: CVS to Subversion Migration

Hi John,

Changing a file "in-flight" makes your working copy out-of-sync with
server copy. This is not a good practice.

Thanks

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.
