Add the bPre11Clients Additional Setting if You Have V10 Clients in Your CommCell Environment

Due to security enhancements made in CPR 2023E, communication from a Commvault Version 11 MediaAgent to Commvault Version 10 clients will not work unless you add the bPre11Clients additional setting to the Version 11 MediaAgent.

1. To the Version 11 MediaAgent, add the bPre11Clients additional setting as shown in the following table.

   For information about adding an additional setting from the CommCell Console, see Adding an Additional Setting from the CommCell Console.

   Property	Value
   Name	bPre11Clients
   Category	CommServe
   Type	Integer
   Value	1

2. Restart services on the MediaAgent.
