CTP version and release version

we have a backup of a database from a release version with version number 9.00.1399 and we wanted to restore it to a server with version number (9.00.1116) CTP release. we were issued a version incopatibility message. is it possible to backup from a 9.00.1399 release with a backup file compatible for a CTP release, is there an available option during backup? thanks!

CTP versions are no longer supported. You should be using the released version of the product.

Ideally, you should be at SP1, as we fixed quite a few bugs there.

Backup is a physical operation. If the structure of the database pages has changed in any way, we have no way to do the conversion during restore. For moving up, we have the logic in the startup code to re-apply the same changes that the upgrade would do. We don't support moving down in versions where the database format is incompatible.
