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
