upgrade overview and prerequisites

requires incremental upgrades from earlier versions. This means, for example, that you need to upgrade from the latest version of 4.8.x to the latest version of 4.9.x to the latest version of 4.10.x to the latest version of 5.0.x.

The current upgrade path can go as follows:

  • 4.6.latest version -> 4.8.any version
  • 4.8.latest version -> 4.9.any version
  • 4.9.latest version -> 4.10.any version
  • 4.10.any version -> 4.10.any later version. You cannot go to an earlier version.
  • 4.10.latest version, 4.10.7 -> 5.0.1

See the following table for latest build numbers.

Starting Splunk Phantom or release Build number Upgrade to version Build number
Splunk Phantom 4.6 4.6.19142 Splunk Phantom 4.8 patch 1 4.8.24304
Splunk Phantom 4.8 patch 1 4.8.24304 Splunk Phantom 4.9 Release 5 4.9.39220
Splunk Phantom 4.9 Release 5 4.9.39220 Splunk Phantom 4.10.7 4.10.7.63984
Splunk Phantom 4.10.7 4.10.7.63984 5.0.1 5.0.1.66250

Do not skip any required versions when upgrading. For example, to upgrade from version 4.8 to version 4.10.7, you must upgrade to version 4.9 before upgrading to version 4.10.7.

Upgrade checklist

Follow these steps to prepare for and upgrade :

Step Tasks Description
1 Make a full back up 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.

2 Do the prerequisites See Prerequisites for upgrading .
  1. Obtain logins
  2. Make sure the instance or cluster nodes have enough available space.
  3. If needed, add a local yum repository or create a satellite server for yum updates.
3 Prepare your deployment for upgrade See Prepare your deployment for upgrade.
  1. Update the operating system and installed software packages
  2. Install the repositories and signing keys
4 Upgrade See Upgrade
5 Conditional Rerun the setup command for ibackup. See Prepare for a backup in Administer .

After all the preparation stages are complete, you can upgrade your instance or cluster. For clustered deployments, after the preparation stages are complete, upgrading your cluster is done in a rolling fashion, one node at a time.

Prerequisites for upgrading

You need the following information before beginning your upgrade:

  • Logins
    • For privileged deployments, user accounts on the operating system for your instance or cluster nodes with sudo or root access on those systems.
    • For unprivileged deployments, you also need the login credentials for the user account that runs . For new AMI or OVA versions of , the user account is phantom.
    • Your Splunk Phantom Community portal login.
  • If your deployment has restricted internet access, you will need a local yum repository or a satellite server from which to get yum packages.
  • A minimum of 5GB of space available in the /tmp directory on the instance or cluster node.

For deployments with restricted internet access, add local yum repositories for upgrade

If your deployment has no access or restricted access to the internet, you must either create a satellite server or local YUM repository for operating system packages and other dependencies. See the Red Hat Knowledgebase article How can we regularly update a disconnected system (A system without internet connection)?

The required upgrade repositories are:

OS version CentOS RHEL
7 [base]

[updates]

[rhel-7-server-rpms]

[rhel-server-rhscl-7-rpms]
[rhel-7-server-optional-rpms]

Prepare your deployment for upgrade

Before you upgrade , you will need to prepare your instance or your cluster nodes by updating the operating system, installed packages, and adding the repositories and their signing keys.

Migrate a privileged deployment to an unprivileged deployment

The AMI and OVA versions of are unprivileged. New AMI and OVA installations run as the user account phantom rather than as root.

If your deployment intends to migrate an existing deployment from a privileged to an unprivileged deployment as part of your upgrade to from Splunk Phantom 4.9 to Splunk Phantom version 4.10, you will use the 'Official Unprivileged Tarball to complete your upgrade and conversion. See Upgrade a single unprivileged instance or Upgrade an unprivileged Cluster.

Update the operating system and installed packages

Follow these steps to update the operating system and otherwise prepare your deployment for the upgrade.

For a clustered deployment, prepare cluster nodes in a rolling fashion, one cluster node at a time.

  1. Log in to the instance's operating system:
    1. For privileged deployments, log in as the root user or a user with sudo privileges.
    2. For unprivileged deployments, log in as the user account that runs .
  2. If you use a warm standby or use ibackup.pyc for backups, you must disable those features before proceeding. If you are not using either of those features, you may skip these sub-steps.
    1. On a single instance deployment of , disable warm standby. See Upgrade or maintain warm standby instances in Administer .
    2. If you are using automation to run ibackup.pyc to make backups, cancel backups that could run during your upgrade window. For example, if you have configured a cron job to run ibackup.pyc, disable that cron job.
    3. Disable WAL archiving for the PostgreSQL database. Set the archive_mode to "off" in the file /opt/phantom/data/db/postgresql.phantom.conf. If your PostgreSQL database is on its own server, you need to disable WAL archiving on that system, not the instance.
      sed -i -e 's/archive_mode = on/archive_mode = off/i' /<PHANTOM_HOME>/data/db/postgresql.phantom.conf
    4. Restart PostgreSQL to make the configuration change take effect.
      /<PHANTOM_HOME>/bin/phsvc restart postgresql-11
  3. Stop all services. For example, as the root user:
    /<PHANTOM_HOME>/bin/stop_phantom.sh
  4. Clear the YUM caches. As the root user:
    yum clean all
  5. Update the installed software packages, excluding Nginx, and apply operating system patches. As the root user:
    yum update --exclude=nginx --disablerepo=phantom*
    Systems which cannot access YUM repositories over the internet need a satellite server. See For deployments with restricted internet access, add local yum repositories for upgrade.

    If you are using the EPEL repository some packages may be upgraded to a version higher than supported by {{PONYDOCSPRODUCT}}. In this case, you want to use the Official Offline RPMs instead of using YUM to get the required versions of package dependencies for {{PONYDOCSPRODUCT}}. See For Splunk Phantom deployments without internet access or unprivileged deployments for instructions.

  6. If a kernel update was included in your operating system updates, restart the operating system. As the root user:
    reboot
    If you did not need to restart the operating system, restart . As the root user:
    /<PHANTOM_HOME>/bin/start_phantom.sh
  7. If a system restart was required, after the system restarts, log in to the operating system as either the root user or a user with sudo privileges.
  8. The install script requires the ability to create jobs in cron. See System requirements for production use. Check that the cron daemon is running.
    ps -ef | grep crond
    1. If the cron daemon is not running, start it.
      systemctl start crond.service
