Query regarding alerts post upgrade

Hi Support Team,

 I am getting the below after I upgraded my Idera SQL DM version from 10.0 to 10.4. I am getting the below alerts for two servers which are running SQL 2000 SP2. Please let me know if there is any fix to clear this alert or is there any other alternative. Please let me know if you need any additional details too.

  

11/7/2019 9:52:32 PM, SQL Server Status on <servername.domain> is Critical.

 SQL Server instance servername.domain - The SQL Server service status is: Unable To Monitor.

 [servername.domain] Error executing Server Details Collector: 'IS_ROLEMEMBER' is not a recognized function name.

 SQL Server Status: Status of the SQL Server service.

Regards,
