I just 'inherited' an application that used IBO3x and am considering
replacing it with IBO4x components. From what I can tell, only the
basic components are used i.e. TIB_Query, TIBO_Query, TIB_Database,
TIB_Connection, the stored procedure component and the DML
component. Also, there does not seem to be much custom SQL written.
Everything is in the components itself.

Would this conversion be painless or are there issues to watch out
for? Thanks in advance.
