These are out of the box workflows..not spd or vs.
A third party migration tool was used to migrate the content and byg process of
repeatedly migrating content over and over and filtering out site columns, we
have identified that the 'workflow version' site column is the culprit.
This column must be corrupt or something, because when we include it in the
migration and start a workflow we get the "the workflow failed to start due to
an internal error." message.

Is there a way to "fix" this column or remove it or something..?
How would I know what properties of this column are causing the problem in the
first place?
Need some guidance please.
