Does storage vmotion break changed block tracking?

Hello

I have observed that after online storage vmotion, the changeid used with changed block tracking is no longer valid. Does that mean that I have to run a full backup after each storage vmotion? (ESXi 5.1)

This is the error I get in the API:

SOAP Fault:
-----------
Fault string: Error caused by file XXXXXXX.vmdk
Fault detail: FileFaultFault
