Version Control can import any version control history using the fast-import format, the de facto standard created by Git. Anything that can be imported into Git can be imported into Version Control. We have helped customers to migrate from Hg, Subversion, CVS, and other set-ups using this method. Plastic is also capable of exporting to fast-export format (besides GitSync), which means that if you ever need to move away from it, you can.
