Does anyone have any intel on what we'll need to do from a linking/paperwork/housekeeping perspective to make this work out?

I'll be just short of status without the merge, but with it, I'll squeak over the line, so I want to make sure there's no action I need to take before the end of the calendar year to pre-link the accounts.

(I'm rejected for status match because I'm not currently holding status, and the points transfer seems unrelated?)
