I just updated a replicator application from something using 5.6 (probably
valid in 4.0 as well) dialect 1 XSQLDA to firebird 1.5 dialect 3.
The only thing I had to do was add the BIGINT data type and the DATE
datatype.
But I can imagine that all your dialect 1 code will run unchanged in the
FB1.5 environment. You can leave all your stuff at dialect 1 which it is,
and FB won't complain.
