Even better, you can run the 9.6 pg_dump against the 8.3 database and get parallelism with "--jobs". On 3/7/19 8:11 PM, Julie Nishimura wrote: Ron, thanksagain. In case if I need to migrate the entire tables, I should be able to use pg_dump and pg_restore for certain tables, even between different versions, right? In case if I need to migrate from 8 to 9?

That's even older than what we just migrated from!!!) No. Make some views (I'd probably make them "month-sized"), COPY each view from the source db to a file, and then COPY each file to it's relevant target table. You should also think about a program named pg_bulkload. https://www.postgresql.org/docs/9.6/sql-copy.html https://www.postgresql.org/docs/8.3/sql-copy.html On 3/7/19 7:53 PM, Julie Nishimura wrote: Thank you Ron! What if dev environment is on 9.6, but prod is on version 8.3? Will posgtres_fdw still be the right option?

What would be the easiest way to do it? In Oracle, I would set up dblink.
