You can upgrade the NAS proxy to the latest versions by downloading the latest version from the Druva portal.

Note:

Before upgrading from Hyrbid Workloads agent to the Enterprise workloads agent, ensure that sufficient free space is available on the disk/drive.
For Windows, the amount of free space required on C: drive should be more than the size of folder C:\ProgramData\Phoenix\NAS\state.

Before triggering an upgrade, it is advisable to close the applications (such as Notepad or Explorer) that are accessing any files or folders in the C:\ProgramData\Phoenix directory.

This topic describes how you can upgrade NAS proxy to the most recent version on a Windows and Linux server.

Note: The NAS proxy upgrade feature is supported from version 4.5 and above. You must manually upgrade to version 4.5 or above to use this feature.

Note: For Windows, if the agent is already installed on a custom location and an auto upgrade is performed, then the agent is installed at:

default install location, C:\Program Files\Druva\Phoenix Agent\ (for agent version prior to 7.0.0)

C:\Program Files\Druva\EnterpriseWorkloads\(for agent version 7.0.0 and later)

Therefore, all the binaries or executable files are moved from the custom location to the default location.

Limitations

If you have installed a hotfix on your existing Druva version, you cannot automatically upgrade to the next version from the Druva portal. You must manually upgrade to the next available version.
If the server running NAS proxy restarts during the upgrade, you must either perform a manual upgrade or roll back the upgrade.
After triggering the update, if you have any ongoing scheduled backup and restore jobs, they will resume after the upgrade.
If the old version is not present the server machine, then upgrade rollback will fail. In this scenario, you must manually upgrade or roll back the client.
