Turning groups on in existing, live courses

Has anyone tried setting groups in a course that already has students enrolled and some forum posts etc. already in it?
Does it work at all?
Can the existing student accounts be assigned to groups retrosopectively?
Who sees the pre-existing forum messages?

thanks for any help.
