Hi

I have to migrate several datasources to custome volumes. There are new requirements and several datasources must be migrated to a new SAN. DPM is in Versio 2012 SP1 with Windows 2008 R2 as OS.

I used the following command:

migratedatasourcedatafromdpm -Dpmservername <name> -Source $ds[0] -Destination $array

-> $ds[0] is my datasource I want to migrate

-> $array is @($vol[0],$vol[1]) where $vol was created using get-dpmvolumes - it listed all my custome volumes correctly

I get the following error about shrinkable thresholds. I don't want to shirnk volumes, I want to migrate them. Unfortunately not sure what I did wrong here.

Error:

Set-DPMDatasourceDiskAllocation : The shrinkable thresholds for the recovery point volume must be calculated prior to shrink. To find shrinkable thresholds, us
e the Get-DatasourceDiskAllocation cmdlet with -CalculateShrinkThresholds parameter. (ID: 32073)
