After an upgrade to NetBackup version 10.5, copying, activating, and deactivating policies may fail for older policies
Explanation:
You can see the message:
The attribute 'useMultipleDataStreams' is false. You must enable this attribute.
NetBackup version 10.5, makes it mandatory for the policies to use multiple data streams, whereas the older policies do not have this attribute.
Workaround:
Edit the older policy, check if the allow multiple data streams option is selected by default. Save the policy.
Retry the operation.
