The sdk to check if vmotion is possible between two hosts has changed in 6.5 to checkmigrate_task. Earlier it was validatemigtration. The validation test types, passed as parameter to the SDKs has even changed in 6.5. I have observed some vmotion incompatible errors when validatemotion is used but for the same scenario, the checkmigrate_task sdk seems to have skipped those validations. Confirm if there are any other SDKs to check vmotion compatibility test.
