This is going to be an amateur question... Could somebody explain me, or point me to a resource where I can find out what is the recommended practice when a live db needs to be replaced with a new version of it that has a slightly different structure? My first guess would be to create the empty new version of the db and insert the data of the old one into it - adding and modifying it when necessary, but I am not sure. What do you usually do in a situation like this? Thanks for the help. Balázs
