   1. For CentOS 7.x:

      Code Block
      sudo /usr/pgsql-9.6/bin/postgresql96-setup initdb

   2. For CentOS 6.x, RHEL 6.x:

2. Transfer settings from the configuration files for your old database version to the new one. Please review the old and new versions of these files:

   Info
   NOTE: It is risky to perform a straight copy of these configuration files. Settings may change. New ones may be introduced. Setting values specific to to the installation may be overwritten in a copy. Please retain a backup of both versions of each file before migrating settings.

   Path to PostgreSQL 9.3 file	Path to PostgreSQL 9.6 file
   /var/lib/pgsql/9.3/data/pg_hba.conf	/var/lib/pgsql/9.6/data/pg_hba.conf
   /var/lib/pgsql/9.3/data/postgresql.conf	/var/lib/pgsql/9.6/data/postgresql.conf

3. Start the service:

   1. CentOS/RHEL:

      Code Block
      sudo service postgresql-9.6 start

   2. Ubuntu:

      Code Block
      sudo service postgresql start

   3. When the service restarts, you can check the cluster status using the following script:

      Code Block
      ./analyze_new_cluster.sh

4. After you have completed the database installation, you must review the port number of the newly installed database, which may have changed between versions of the database software. That new port number must be applied through the 

   D s item
   item software

   . For more information, see Change Database Port.

5. If all is well, restart the platform. See Start and Stop the Platform.
