I use SmartGit/HG with an old svn-repository. So it is not a git-repository.
I would like to create a new branch from a former revision in SmartGit. Is this possible?
In the end I would like to have a new folder on my local disk, where I have the full branch-files and in the old existing folder I will have the full trunk-files.
First, make sure you have cloned the SVN repository with SmartGit/Hg, not with git-svn (usually SmartGit/Hg will warn you about that when opening such a repository). Then:
Now, your new branch will be present in the SVN repository and should show up in SmartGit/Hg's Log as a remote branch as well.
