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	Do the prerequisites	See Prerequisites for upgrading . Obtain logins Make sure the instance or cluster nodes have enough available space. 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.
