Hello Roger,

We just use FlameRobin (freeware, see Firebirdsql.org website for
link) to do this. There is a Generate Rebuilt script for different
objects, which takes care of dropping and recreating the dependent
objects.

Other tools can accept an original and target database and generate a
script to convert it.
