Verify that VMs to be migrated are included in DRS anti-affinity rules or groups. Checking the Cluster settings menu via vSphere ClientvSphere Client or using the following PowerCLI Code (a PowerCLI version greater than 6.5.2 is required. ) is recommended

The following PowerCLI Code can be used to locate configured DRS Groups:

Get-VM | 
Select Name, @{N='DRSGroup';E={$script:group = Get-DrsClusterGroup -VM $_; $script:group.Name}},
    @{N='GroupType' ;E={$script:group.GroupType}}

 

The following PowerCLI Code can be used to locate configured DRS Rules:


Get-DrsRule -Cluster 'TSA-WDC-65-Clus01' -VM "Oleg-VMC-SQLAAG02"

 

Remove all VMs to be migrated from all DRS overrides (including rules and groups) using vSphere Client or PowerCLI.

NOTE: A DRS anti-affinity rule containing just two VMs must be removed completely. Removing one VM at a time is not supported.

 

Ensure that all required networks are available in the target SDDC. It can be helpful to move a test database workload first, to verify that the network connectivity functions as expected. Refer to Standalone SQL Server Migration for detailed information about obtaining the network configuration.
