In addition to what Mladen and Joel wrote...
We did for DB2 to Oracle about a year or so, ago. We ended up writing
our own JDBC migration utility, and it really wasn't too difficult. I
think it took four hours to write *and* test. We had logging,
exception handling, verification, etc.
Of course, that is a two edged sword. As with anything you write
yourself, you end up with an almost infinite amount of control, but
for a minimum of work, have to have:
* a fairly small number of changes, i.e. same number of columns with
* some degree of java expertise.
After we used it for DB2, we then took it to the next level and
extended it to allow us to migrate Oracle to MySQL, etc.
As already noted, there are off the shelf migration tools out there,
as well as part of the database itself. It depends, as always, on
your needs and areas of expertise.
