-------------------
No, the files will not be "migrated" until you migrate them or "rebuild all"
all the parts. If saved in 5.3, though, they will no longer be accessible in
5.0. If the files are opened in 5.3 and closed without saving, they will
still be accessible in 5.0.

-------------------
Theoretically, but keep backups of the old versions in case it can't. There
are occasional problems. Also, it's probably safe to say that trying to open
a project that was last saved several versions prior is inviting problems.
