Currently the SharePoint task for uploading a document appears to be performing a delete and then upload of the document. This causes the existing document to lose it's history. Please develop the following new tasks:

• Check Out a Document (if the document does not exists then no error should be generated)

• Check in a document

Alternatively the upload to SharePoint task should have a check box that says "Preserve current document's versioning history".

Thank you
