I use a Hyper-V HA-Cluster with Windows Server 2012 R2 in production mode. Is it necessary to remove all cluster shared volumes which use the Microsoft DSM?</P> Wed, 04 Jun 2025 13:27:47 GMT ITPIT 2025-06-04T13:27:47Z https://community.netapp.com/t5/ONTAP-Discussions/Replace-Microsoft-DSM-with-Data-ONTAP-DSM/m-p/141846#M31403 <P>Hi all,</P> <P>&nbsp;</P> <P>I'm looking for a best practice description how I can switch over from Microsoft DSM to Data ONTAP DSM 4.1.

I got the wrong DSM installer. After installing the right package the MPIO DSM claiming automatically switched over after reboot.</P> Fri, 03 Aug 2018 11:50:00 GMT https://community.netapp.com/t5/ONTAP-Discussions/Replace-Microsoft-DSM-with-Data-ONTAP-DSM/m-p/141891#M31416 ITPIT 2018-08-03T11:50:00Z
