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
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 :-)
