Hello, what is the best way to migrate from PostgreSQL
8.3.11 on x86_64-redhat-linux-gnu to
PostgreSQL 9.6.16 on x86_64-pc-linux-gnu server, with minimal downtime?
The caveat is the source has about 80 databases overall
almost 30 TB. I could migrate the smallest ones (up to 1 tb) using pg_dump and pg_restore, but the largest hot database is almost 17 tb, and I am not sure how to approach this effort in a better and efficient way?
Thank you!
