1. Stop the platform:

   Code Block
   service trifacta stop

   
   

2. Install the upgraded version. Below, PostgreSQL 9.6 is installed.

   Code Block
   sudo apt-get install postgresql-9.6 postgresql-server-dev-9.6 postgresql-contrib-9.6 -y

   
   

3. Stop PostgreSQL:

   Code Block
   sudo systemctl stop postgresql service stop postgresql service postgresql stop

   
   

4. Upgrade the PostgreSQL 9.3 version to PostgreSQL 9.6, using the newly installed version:
   

   D s property overflow

   Code Block
   sudo su - postgres -c '/usr/lib/postgresql/9.6/bin/pg_upgrade \ -b /usr/lib/postgresql/9.3/bin -B /usr/lib/postgresql/9.6/bin \ -d /var/lib/postgresql/9.3/main/ -D /var/lib/postgresql/9.6/main/ \ -O "-c config_file=/etc/postgresql/9.6/main/postgresql.conf" \ -o "-c config_file=/etc/postgresql/9.3/main/postgresql.conf"'

   
   

5. Remove the old version of PostgreSQL (9.3):

   Code Block
   sudo apt-get remove postgresql-9.3 -y

   
   

6. Restart PostgreSQL and the platform:

   Code Block
   service postgresql start service trifacta start

   
   

Transfer Settings

For all operating systems, you must transfer the settings from your old version of PostgreSQL to the new one.

1. Update the port number and any other settings in the platform configuration. 

   D s config
   method triconf

   
   
   1. Replace all instances of the PostgreSQL port number for the earlier version and replace with the desired port number for the upgrade version. 
      

      D s pssql port

   2. Make the above changes and save the file.

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. Verify datestyle setting.

   Info
   NOTE: If the PostgreSQL instance used by the D s platform was not created as part of the D s item item installation , please verify that the PostgreSQL datestyle value begins with ISO. For more information, see Configure the Databases.

   
   
   

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