Upgrade overview checklist

Follow these steps to prepare for and then upgrade :

Step	Tasks	Description
1	Identify your upgrade path.	See: Upgrade path for Splunk SOAR (On-premises) privileged installations Upgrade path for Splunk SOAR (On-premises) unprivileged installations You will need to plan your upgrades by identifying your currently installed Splunk Phantom or Splunk SOAR (On-premises) release, then path to your destination release. You must follow the path from your currently installed release to the desired destination release.
2	Make a full backup of your deployment	Make a full backup of your deployment before upgrading. See Backup or restore your instance in Administer . For single instance deployments running as a virtual machine, you can create a snapshot of the virtual machine instead.
3	Perform the prerequisites	See Prerequisites for upgrading . Obtain logins Make sure the instance or cluster nodes have enough available space. In order to upgrade Splunk SOAR (On-premises) to release 6.2.0 or higher, you may need additional disk space. Additional disk space may be needed because the PostgreSQL database is being migrated from PostgreSQL 11.x to PostgreSQL 15.x. See Additional disk space requirements for upgrading PostgreSQL in this topic for more information. Conditional: Turn off warm standby. See Warm standby feature overview Conditional: Turn off scheduled backups. For example, if you scheduled backups with a cron job, deactivate the cron job to turn them off.
4	Prepare your system for upgrade	See Prepare your Splunk SOAR (On-premises) deployment for upgrade.
5	Conditional: Convert a privileged deployment to an unprivileged deployment.	See Convert a privileged Splunk SOAR (On-premises) deployment to an unprivileged deployment.
6	Upgrade	See Upgrade . After all the preparation stages are complete, you can upgrade your instance or cluster. For clustered deployments, after the preparation stages are complete, upgrade your cluster in a rolling fashion, one node at a time.
7	Conditional: Repair indicator hashes for non-federal information processing standards (FIPS) deployments.	If you are upgrading a non-FIPS instance, you must run the following script after running the installation script: repair_520_indicators.sh. That script is located in <$PHANTOM_HOME>/bin/. You may optionally pass the batch size as an argument: repair_520_indicators.sh <batch_size>. The default batch size is 1000. You can restart the script at any time. The script terminates after execution. In clustered configurations, run this script on any single node. In configurations using warm standby, run this script only on the primary system.
8	Conditional: Rerun the setup command for ibackup	See Prepare for a backup in Administer .
9	Conditional: Reestablish warm standby.	See Warm standby feature overview.

Prerequisites for upgrading Splunk SOAR (On-premises)

You need the following information before beginning your upgrade:

• Logins
  • For unprivileged deployments, you need the login credentials for the user account that runs . For new AMI versions of , the user account is phantom.

    See What's new in 6.0.0 in Release Notes for important information about the change to the default administrator user account.

  • Your Splunk Phantom Community portal login.
• A minimum of 5GB of space available in the /tmp directory on the instance or cluster node.
• Enough free disk space in <$PHANTOM_HOME>/data/ and its subdirectories to allow for the upgrade of PostgreSQL. See Additional disk space requirements for upgrading PostgreSQL in this topic for more information.
• Make note of the directory where is installed.
  • On an unprivileged AMI, or virtual machine image deployment - /opt/phantom, also called <$PHANTOM_HOME>.
  • On an unprivileged deployment - the home directory of the user account that will run , also called <$PHANTOM_HOME>.
• Conditional: If your deployment uses the warm standby feature, turn off warm standby. See Warm standby feature overview.
• Conditional: Turn off scheduled backups. For example, if you scheduled backups with a cron job, deactivate the cron job to turn them off.

Additional disk space requirements for upgrading PostgreSQL

In order to upgrade to Splunk SOAR (On-premises) release 6.2.0 or higher, the disk partition that holds <$PHANTOM_HOME>/data/ and its subdirectories needs to be large enough to hold a copy of both the PostgreSQL 11.x database and the PostgreSQL 15.x database.

• If you have mounted the <$PHANTOM_HOME>/data/db/ partition elsewhere, you must make sure that mount is large enough to accommodate the upgrade.
• During the upgrade, your existing Splunk SOAR (On-premises) PostgreSQL 11.x database will be moved to <$PHANTOM_HOME>/data/db/db.old/. This copy is used as part of the migration to copy your existing data into the new database, and as a data integrity precaution.
• After the upgrade, your new PostgreSQL 15.x database will be located in the same location as the previous PostgreSQL 11.x database, <$PHANTOM_HOME>/data/db/.

Do the following steps before upgrading to make sure you have sufficient space for the upgrade:

1. Check the size of your current PostgreSQL 11.x database directory.

   du -sh <$PHANTOM_HOME>/data/db/  

   Example output:

   [phantom@localhost db]$ du -sh /opt/phantom/data/db/
   102G /opt/phantom/data/db/
   

2. Use the output from the disk usage command to calculate the minimum requirement of 225% (2.25 times) the disk space.

   <du output> * 2.25 = <minimum required disk space to upgrade PostgreSQL>

   Calculation:

   102G * 2.25 = 229.5G
   

3. Locate your <$PHANTOM_HOME>/data/db/ directory.

   grep "<$PHANTOM_HOME>/data/db/" /proc/mounts

   If this command returns nothing, your directory is mounted in the default location <$PHANTOM_HOME>/data/db/.

4. If your current <$PHANTOM_HOME>/data/ partition does not have at least as much available space as calculated in step 2, you must increase the size of the <$PHANTOM_HOME>/data/ partition to have at least that much available space.
