# Verify Prerequisites for Commvault Grid Upgrade

To prepare your Commvault environment for the upgrade using the HSX ISO released in June 2025 - 11.36 Hyperscale ISO 3.2506 or 11.32 Hyperscale ISO 3.2506 or 11.40 Hyperscale ISO 3.2506, verify that the following minimum Commvault versions are installed:

Base Commvault Version | Minimum version for OS Upgrade
--- | ---
11.32 | 11.32.102 or later
11.36 | 11.36.60 or later
11.40 | 11.40.6 or later

To prepare your Commvault environment for the upgrade using the HSX ISO released in June 2025 - 11.36 Hyperscale ISO 3.2506 or 11.32 Hyperscale ISO 3.2506, verify that the following minimum Commvault versions are installed:

Base Commvault Version | Minimum version for OS Upgrade
--- | ---
11.32 | 11.32.102 or later
11.36 | 11.36.60 or later
11.40 | 11.40.6 or later

To prepare the Commvault Grid nodes for the OS upgrade, verify the following minimum Commvault Grid Platform versions are installed on each node:

Commvault Grid Platform | Minimum Commvault Grid Platform Version
--- | ---
11.32 | 2.2506
11.36 | 2.2506
11.40 | 2.2506

Note

- Commvault Grid MediaAgents should always be running the same Commvault platform and maintenance release as the CommServe.
- Verify that ICMP/PING requests between the default gateway and the HyperScale nodes are enabled. If requests are disabled, the network settings must be updated to allow ICMP/PING to the default Gateway for the duration of the HyperScale Platform upgrade.

## Virtualized CommServe on Commvault Grid Appliance

If a CommServe virtual machine is installed on one or more of the Appliance nodes, you must move the CommServe off the Appliance before proceeding with the upgrade. Rebuild the CommServe on a separate server outside of the Commvault Grid cluster. For more information on rebuilding the CommServe software, see CommServe Hardware Refresh. The Commvault Grid upgrade process will not proceed if the CommServe is running on a Commvault Grid node.
