The implications of mixed-revision working copies on tree conflicts have been discussed on the users@ list a lot. See for instance http://svn.haxx.se/users/archive-2009-08/0748.shtml To avoid problems resulting from mixed-revision copies, URL->URL copies should always be used to create branches. Use working copy -> URL copies only if you really need to create copies of things which differ from anything else in the repository, and know how to deal with consequences. For instance, the Subversion project itself creates its release tags from working copies, after adjusting version numbers from e.g. 1.6.x to something fixed like 1.6.12. This avoids version-numbering churn on the release branch itself. Stefan
