I recently upgrade some of our databases from 9.6 to 14.1. I used pg_upgrade and there wasn’t any diffrences in code level. Everything was perfect Best regards Abbas On 11 Jan 2022, at 5:21 PM, Daulat <daulat.dba@xxxxxxxxx> wrote:

Hello,
Have a look at https://www.postgresql.org/about/featurematrix/ for the
differences between versions. For code level impact (which will be very
small, maybe non-existant), you may read the release notes of the
versions 11 thru 14.
https://www.postgresql.org/docs/11/release.html
https://www.postgresql.org/docs/12/release.html
https://www.postgresql.org/docs/13/release.html
https://www.postgresql.org/docs/14/release.html
The topic upgrading is well described at
https://www.postgresql.org/docs/current/upgrading.html
If your database isn't large, I'd recommend pg_dump + psql, but if it's
large, pg_upgrade is a must.
Regards,
Holger
