We need to upgrade Postgres version from current version of 9.6 to higher version 12.x. Since, we have Pega version as 8.3, can you please suggest will this work good for us.
@MohitK73 please check the Platform Support Guide carefully.
That combination is not supported. PostgreSQL 12 is supported from 8.6 onwards and PostgreSQL is only supported for the Tomcat webserver, or JBoss with WAR installations only.
