All SCM tools will frustrate anyone migrating from one to another. I've done migrations among most of the major commercial SCM tools and had to write training documentation for developers. You do have to realize that if the underlying model for version control is different, then commands and terms will be different even if they share the same name like "checkout." And what you think you can or want to do might not be what you really should do. So expect some initial frustrations and a lot of referencing of the man pages, documentation, blogs. You're going to have to unlearn a lot of behaviors that may be second nature to you. But at the end, you'll get a much better appreciation of what each tool gets right and an understanding of their limitations.
