I registered a project under LEEDv4 (#100038645) because my anticipated completion was past the LEEDv4 sunset date. Now that the registration deadline for LEED 2009 has been extended to 10/31/16, I assume the corresponding sunset date has been extended to 10/31/22 or thereabouts. The project and associated documentation should be complete prior to the LEED 2009 revised sunset date. I would like to change my project registration from LEEDv4 to LEED 2009. Any word as to whether this will be possible?
