NetWorker: "NetWorker Version" in client properties not updating after NetWorker client upgrade

After upgrading the NetWorker client software on a system, the clients "NetWorker version" is not updated in the client properties. 

The following commands show what the version of NetWorker is installed on the client:

Linux:

strings /usr/sbin/nsrexecd | grep "@(#) Release"

wmic product where "PackageName = 'NwClientMsi.msi'" get Name, Version

The client is not configured in a Protection Group as indicated by the (!) next to the client name:

When the NetWorker client software is upgraded, the "NetWorker version" shown in the client will not be updated until the client is backed up. This is as per design.

When the client shows (!) next to the name it means it is not protected in a NetWorker protection group. And no backups of the client are performed.

Example scenario where this might be observed. The client who's version is not correct in the client properties is the physical node of a cluster. The cluster shared data is protected through a client resource created using the logical cluster name. The physical nodes and their local file systems are not being backed up, or are backed up infrequently.

Whether the example scenario is applicable or not, if there has been no backup of the client since the NetWorker client software was updated, the "NetWorker Version" details in the client properties will not be updated to reflect the new client version.
