I  can  only  confirm this. The division I work for develops their own
data  migration _framework_ which is then specialized for the specific
migration  project.  This  is done via customization (XML configs) and
Java code.

Since  each of the previous (and current) migrations required a lot of
data  validation, cleanup as well as changes to the data structures, a
run-of-the-mill  tool  would  have  probably caused a lot more trouble
than it would have solved.

So yes, I definitely also recommend the do-it-yourself approach :-)
