can I upgrade a database from filmmaker pro 12 to pro 17 directly
Welcome, myk !
You may OPEN a database/file created in FileMaker 12 directly with FileMaker 17. There is no "upgrade pricing path" for FM 12 to FM 17. The latest that qualifies for upgrade pricing is FM 15.
FileMaker Store: Purchase single licenses of FileMaker Pro Advanced.
