VsanVdsGetMigrationPlan(vsanVdsGetMigrationPlan)

Computes a migration plan to convert the VSS instances per host in the cluster to a newly created VDS. The VDS preserves all settings of the VSS, and all consumers (vmknics, VM vNICs, pNICs) are considered as part of the migration. The VSS vSwitch and portgroup instances across the hosts are matched to each other by common name. It is expected that hosts have a uniform configuration, and issues will be raised in the migration plan if deviations are found. Any deviations will still be carried over, but may require renaming of portgroups and additional VDS portgroups to resolve the conflicts. The migration plan is defined to be safe, i.e., the effective data path for all impacted VMs, vmknics and so on are going to be using the same settings as before the migration. The only change will be in any additional pNICs added as part of the migration.
Note: This API can also be used to create a new VDS without any portgroups, but with the physical NICs attached, and with good settings for vSAN, by simply passing the vswitchName as NULL.

VsanVdsMigrateVss(vsanVdsMigrateVss)

Perform a migration to convert the VSS instances per host in the cluster to a newly created VDS. The VDS preserves all settings of the VSS, and all consumers (vmknics, VM vNICs, pNICs) are considered as part of the migration. The VSS vSwitch and portgroup instances across the hosts are matched to each other by common name. It is expected that hosts have a uniform configuration, and issues will be raised in the migration plan if deviations are found. Any deviations will still be carried over, but may require renaming of portgroups and additional VDS portgroups to resolve the conflicts. The migration plan is defined to be safe, i.e., the effective data path for all impacted VMs, vmknics and so on are going to be using the same settings as before the migration. The only change will be in any additional pNICs added as part of the migration.
Note: This API can also be used to create a new VDS without any portgroups, but with the physical NICs attached, and with good settings for vSAN, by simply passing the vswitchName as NULL.
If a migration plan is passed in, the API makes sure that no changes have happened and that the migration plan is still current. This can be used to make sure that the migration plan that the user reviewed doesn't deviate from the actual migration performed.
If there are any inaccessible or orphaned VMs found the migration will not be performed. This is a safety measure as such VMs may loose their networking.
If there are any inaccessible hosts in the cluster the migration will fail.
The migration will fail if there is any infraVm on ESX with version prior to 6.5.0d, due to the missing of API support on the hosts.
A minimal version of 6.0 is required for all hosts to be migrated for the NetIOC setup task. Also the VDS version will be 6.0.0 if there is any 6.0 host to be migrated, otherwise 6.5.0.

This API by default requires DVSwitch.Create and DVSwitch.Modify on RootFolder, and System.Read on cluster. Host.Inventory.EditCluster on hosts is required if hosts parameter is provided.

VsanVssMigrateVds(vsanVssMigrateVds)

Perform a migration to convert the VDS instance in the cluster to a newly created VSS on each host. The VSS preserves all settings of the VDS, and all consumers (vmknics, VM vNICs, pNICs) are considered as part of the migration. The VSS vSwitch and portgroup instances on the VDS are matched to each other by common name. It is expected that hosts have a uniform configuration. The VDS will be deleted if no hosts and virtual machines are connected to this VDS after the migration completes. If there are any inaccessible or orphaned VMs found, the migration will not be performed. This is a safety measure as such VMs may lose their networking. If there are any inaccessible hosts in the cluster the migration will fail as well.

This API requires DVSwitch.Delete and DVSwitch.Modify on vds, extra privilege check might be needed depends on what is being migrated.
