Get an error about backup version when trying to upgrade agents after upgrading RMAD.
原因
Cannot create backups due to Backup Agent incompatibility between RMAD version and Backup Agent on the DC. When trying to upgrade the agent operation status shows "Failed: Cannot install Backup Agent. Details: The Backup Agent version 8.5.1.5077 has been detected. The agent version 8.6.1.6026 is required."
After the error has been shown, take note of the DCs that have issues upgrading.
For each DC with the issue, open the Services Snap-in (services.msc) and restart the "Quest Backup Agent" service.
Return to the Backup Agent Management node on the Rmad console and retry upgrading the Backup Agents for the failed DCs. The result should be succeded.
Right click the Backup Agent Management node on the Rmad console and select "Discover all Backup Agent Instances" to refresh the console's agents.
