One of the changes I want to make is to make all file paths relative to the storage location (unless files are not being managed by MobileSheetsPro, in which case the full path must be saved). Once I do this, in theory you could easily copy your database between versions, because the storage location isn't stored in the database, and all of the files would be relative to whatever location you've picked on each OS. Until this is done, just storing the storage location in the database isn't enough, because the full path to every file is still stored in the database and has to be updated (which is what happens when you restore a backup file). The real hope is that the upcoming sync features will make it easy enough for people to sync up changes that they won't need to mess with copying things between devices.
