I am working on it, but because there is a huge amount of data, all
converting and exporting lasts very long.
When I am ready, I will ask for the adress to send it to.
I am very interested in giving the folks of firebird the possibility
to reproduce the problem and to solve it.

I tried it one time and there where no duplicates wiht interbase 6.5
trial version.

I will test it for 3 more times and then repeat the test with firebird
3 times. My colleague will do the same testing.
After that, I can say more.
