Thanks for that idea Marnen, I will take a look at Foreigner..
I think I would still have problems importing one database into the other ... Say I import "Clients" and all the ids get updated I would need to update all the client_id values on say the adresses table.... but the addresses table may not be imported yet so would not cascade update. I think you are saying - Change all the primary keys on one of the databases first and then do the merge and the keys will be in mutually exclusive ranges.. I guess I would then possibly need to reset the sequences on the DB.. Whichever way I look has drawbacks!
