Before upgrade to APM10.8 need to go to 10.7 HF84 and postgres upgrade is mentioned in this HF version
But when I refer to "APM_Compatibility_Guide_10.8.xlsx",In the "APM DATABASE" item on the "APM Components" sheet Postgres version 9.6.2 seems to support it.
Currently using APM10.7-Postgres9.6.2
Would like to know if the Postgres upgrade is absolutely necessary
Release : 10.7.x /10.8
1. 10.7 HF84 or above is the pre-requisite to upgrade to 10.8 GA
2. Postgres 9.6.2 to 13.x upgrade is not mandatory ... we added the support for Postgres 13.x from HF84 release, but not its mandatory to be upgraded
We added the support for newer versions of Postgres as 9.6 was reaching end of life and there are security vulnerabilities to be addressed
