Errm - step 3 should be step 1. ;-)

Ambiguous queries involving multiple tables will be your main gotcha. FB
will reject multi-table queries (joins, self-joins, subqueries, unions)
that don't have fully qualified column names. (It's fine for the
qualifiers to be table aliases).

For example, some ambiguous system queries hard-coded into the IBConsole
program don't work in Firebird.

Another is "mixed syntax" inner joins. IB allows these (with unpredictable
output outcomes); FB will block them. That is, mixing the SQL-89
comma-list syntax for table names with the SQL-92 JOIN...ON syntax. Use of
both (as in "one" or "the other" is fully supported.

New language syntax introduced into IB 6.5 and later is not supported.

Firebird has a number of new reserved words, as well - see the ReleaseNotes.

Can't think of anything else at the moment...
