I have tried all methods of upgrading using the upgrade files provided in the admin folder; none of them work. I have installed a clean version of 2.0.3, is there a way to transfer the data from 1.4 to 2.0.3 without having to manually re-enter all 171 people in my tree?
The best approach would be to find out why the upgrade scripts don't work -
if you post any error messages then will try to help.
Other than that the only approach I can think of is to use gedcom - export, then import - I think you will lose some data that way but it should capture most of it.
