TIBQuery isn't an IBObjects component.

Don't try to mix the IBX components with IBO - it won't work.

Don't use a query component for DML operations like inserts. Use the
TIB_DSQL component for the insert; and parameterise all of the columns for
the destination database.
SQL property is:

INSERT INTO BLAH (Col1, Col2, Col3, ...)
VALUES (:Col1, :Col2, :Col3, ....)

This way, you can do this in [BeforeExecute]
with MyDSQL do
begin
if not Prepared then Prepare;
ParamByName('Col1').AsSomeType := AdoQuery1.Acolumn.AsSomeType;
ParamByName('Col2').AsSomeOtherType := AdoQuery1.Acolumn.AsSomeOtherType;
....

end;

In most cases, you will be able to use the actual As... casting methods to
transform your mismatched data.

The Execute call will post your inserts. Break the operation up into
batches and commit about every 8 - 10,000 inserts.
