Hi Edson, Maybe the best option is what Jack has already suggested, to have all in 1 DB in separate schemas (if tables are not already organised in separated schemas...)... But I am not sure I understand well problems:

Also, it is very > hard to implement with JPA. 1) I guess data just need to be coppied in proper order... though, Postgres have deffered constraint feature, what means, FK will not break transaction until end (all trans commited) - untill all data copied... 2) I just wonder On what way it is possible in MS SQL Server or any other db engine? (to have FK to foreign table... ) Thanks, Misa
