Having Trouble getting the correct drivers needed.

I received an alert for degraded virtual disk performance. when checking the logs, I get this error message:The current driver version 6.600.21.08 (megaraid_sas) is older than the required driver version 6.803.21.00 (megaraid_sas) for a controller of model 0x1F38: Controller 0 (PERC H710 Mini)

The client has a PowerEdge R520 running Windows Server2012R2 Datacenter.

Any help is appreciated!
