Dear Team,
we are planing to RHEL OS upgrade from 6.7 (Current version) to 8 version.
currently postgresql-12.6 version running on the server , we have upgraded OS on test DB server from 6 to 8 version during OS upgrade postgresql-12,11 and other package is removed and Postgresql is not started. that why my DB is crashed , can you please suggest what is best way to upgrade OS.
And also confirm postgresql-13 support RHEL 6 version because during installation its showing postgresql13-server not found.
