Re: Merging two databases

Hi,
Obviously it will always depends on the constraints in your schema, but
why do not dump the databases out and import it into a single one
properly? Once you get the new database, it should be easy to catch up
with the 2 databases before the switching (with statements like
insert/update into Newdb tables ...(select from Olddb tables)).
It is up to you, this is to avoid replication settings, however using
replication could be a good thing for future replication experiences.
