The other way to ask. If I have two 99% schema similar databases. The old one might contain few columns that does not exist in the new one and contain constrains that the new DB does not have. In that case, what's standard to do this?
Since they are 99% similar in schema, can I do "data dump" only ? will that work?
If owner for database between Old and new DB are different, do I must add that owner in by create new role?
appreciated,
Steven

Hi all,
I am dumping both schema and data from old database to new one. The new database schema is somehow contain slightly different schema then the old one. When I do restore it shown alot errors related with constraints. How can I dump and to restore from old to new without dealing with constraint and just forces data dump to where it suppose to belong?
