Can projects continue to use VCS methodologies that may become inconsistent with VCS Version 3 requirements?

In some cases, the VCSA may ask a methodology developer to make minor revisions to a methodology. However, all VCS methodologies approved before 8 March 2011 will remain valid until 8 September 2011. If more extensive revisions are required and a methodology must be put on hold, projects may still continue to use the methodology for a grace period of 12 months (for non-AFOLU methodologies) or 18 months (for AFOLU methodologies). The list of methodologies and their status is available on the VCS website.
