Application software migrations can require multiple jumps like that.

Usually in those situations, though, it's /really really old/ 
application/DB/OS combos.

To migrate the applications to latest versions of our applications,as

levels of our postgresql upgrades to support the different versions

We are planning to upgrade postgres versions  from 9.6 to 10 in the

Why upgrade in steps?

You can go directly from 9.6 to 14 (or 15 or 16) either using pg_upgrade
or through dump/restore

I don't see a need to install Postgres 10 (or 12) if you want to go to 14
