Annual Pass Upgrade and Photopass

Heading to WDW in a couple weeks. We currently have 8 day base tickets but plan to upgrade to annual pass on day 2 with DVC discount (Gold). Has anyone upgraded yet under new program? My question ties into new Photo pass inclusion, will it automatically show on MDE once tickets ARE upgraded? Also, if we take some pics at Xmas party the night before upgrading, do you think those would download also? Thoughts? Anyone work through this scenario yet? Thanks for your feedback!

We upgraded on day 2 and photos from day 1 showed up even with a refund of price paid for memory maker. Might be different because we had purchased MM prior to our trip.
