Symptoms

While performing the RHEL6->RHEL7 migration procedure for the BA DB node, the error is faced:

# python el6_ba_migrate.py --db=192.0.2.2 --backup
...
Exception: Internal error: /bin/sh /bin/sh -c rpm -ql postgresql96-server | grep /postmaster$ failed with code 1 saying: STDOUT:

The source BA DB host does not appear to have PostgreSQL server version 9.6 installed:

[root@bmdb ~]# rpm -qa | grep postgres | grep 9.6
[root@bmdb ~]#

The required hotfixes are installed.

Cause

After installing KB130373 hotfix, required for the migration, the action to update billing was not performed.

Resolution

Complete the Billing update:

# /usr/local/pem/bin/pa_updates_installer --update-billing

Retry the migration.
