2. **Distributed Resource Scheduler (DRS) rules:** DRS VM-VM anti-affinity rules must be configured in a way to have at least (N+1) hosts in the cluster, where N is the number of VMs part of DRS rule.

3. **Failures To Tolerate (FTT) violation:** To prevent data loss, change VMs configured with a vSAN storage policy for Failures to Tolerate (FTT) of 0 to a vSAN storage policy compliant with [Microsoft SLA](https://www.microsoft.com/licensing/docs/view/Service-Level-Agreements-SLA-for-Online-Services?lang=1) (FTT=1 for up to five hosts in a cluster and FTT=2 for six or more hosts in a cluster) and ensure host maintenance operations can carried out seamlessly.

4. **Remove VM CD-ROM mounts:** VMs mounted with "Emulate mode" CD-ROMs block host maintenance. Ensure CD-ROMs are mounted in "Passthrough mode".

5. **Serial/parallel port or external device:** If you are using an image file (ISO, FLP, etc), ensure that it is accessible from all ESXi hosts in the cluster. Store the files on a datastore that are shared between all ESXi Servers that participate in the vMotion of the virtual machine. Refer to [Broadcom KB article](https://knowledge.broadcom.com/external/article/324829/vmotion-fails-with-the-compatibility-err.html) for more information.

6. **Orphaned VMs:** In the case of an orphaned virtual machine, the Virtual Machine (VM) needs to be either re-registered if possible (if it hasn't been deleted) or removed from inventory. Refer to [Broadcom KB article](https://knowledge.broadcom.com/external/article/312831/virtual-machines-appear-as-invalid-or-or.html) for more information.

7. **SCSI shared controller:** When using SCSI bus sharing use with bus type as "Physical" for VMs. VMs connected to Virtual SCSCI controllers will be powered-off. Refer to [Broadcom KB article](https://knowledge.broadcom.com/external/article?legacyId=2147661) for more information.

2. Ensure that the VM isn’t installed with a VM-Host "Must run" DRS rule. Additionally, verify that these applications are compatible with upcoming versions of the VMware stack.
