Alternatively, you could upgrade the old DB by running the 1.12 version 
of upgrade.php against it and then backup the DB using mysqldump. 
Restore that to the new DB. 6 of one, 1/2 dozen of the other.

Either of these will wipe out anything in your new DB, so if there's a 
significant amount of data in there currently, you'd need to export 
that.  It will come down to which has few pages to export as to which 
version you choose to export via Special:Export.

Personally, I'd recommend upgrading the 1.12 version to 1.14 before 
starting this.
