Our system team would require us to upgrade the OpenSSH and OpenSSL to newer versions
Current version: OpenSSH_8.1p1, OpenSSL 1.0.2u
Target version: 9.2.112.2000, 3.0.13.1000
Do you have any concerns or know of any compatibility issues with these versions as compared to our current versions of the CA Harvest SCM Agent on AIX?
CA Harvest Software Change Manager 14.5 and higher on Unix, Linux and zLinus
Those upgrades should be transparent to Harvest. In other words, we are not aware and don't think the upgrade will post some issues for Harvest.
If you have configured for OpenLDAP authentication you can test with the hauthtst command after the change to be sure it's still working. Also, as a best practice, if you have DEV env you should upgrade in DEV env and make sure no issue before upgrade to Prod env.
