An upside to SAAS, I guess -- if the user data lives on your servers in a reasonably structured format you can try to migrate it, and your migrations don't have to work across too many versions if that's difficult (unlike file format compatibility, which is a long term commitment.)
Of course, that only works to a certain extent. Removed features can't be "migrated" cleanly, and often config files (or worse -- code written by users in most DSLs) aren't well-structured enough to make migration straightforward.
