Agencies can use any S2S version to retrieve applications regardless of which version the applicants used to submit the applications. The only constraint is large application submissions (e.g. exceeding 200 megabytes). If V2.0 is used by the Applicant to submit large applications, the Agencies will need to use V2.0 to retrieve the applications through S2S. Alternatively, the agencies can retrieve the large applications using the online user interface.
Web services versions have no impact on the form versions used. Any version of the forms can be submitted and retrieved by any S2S version.
