Hey there,
we ran a SP 2013 Preview server with some site collections.
The installation of SP2013 RTM is independent of this and runs on another server. Now while trying to import some Site Collections Backups (bak-Files) via the restore-spsite command I'm experiencing an error ...
<nativehr>0x80070003</nativehr><nativestack><nativestack>
Isn't the option available to move site collections between Preview and RTM?
Best regards! Thomas
