Racking under the pellicle doesn’t have any impact - it’s throughout the beer. The pellicle only forms at the surface and is a by-product of oxygen exposure. It’s a side effect of the infection, but not the infection itself.
Drinking it fast is a good option, just make sure you don’t keep them around any longer than necessary. Swing-cap bottles are pretty safe, since they’ll tend to leak if they get over-pressurized.
I usually give my glass carboys a thorough soak in oxy-clean for at least 24 hours with the hottest tap water I dare to put in them, which is just barely warm. Fill it to the top. Then a good 24 hour soak with star-san for at least 24 hours. I haven’t done a mixed fermentation batch yet that has carried through after that.
Boil silicon stoppers and any high temp parts you have. Plan on replacing auto-siphons, hoses, bottling wands, and any other plastic or soft cold-side parts that touch the infection. Or just dedicate these to mixed fermentation. Glass can be sanitized, so don’t worry about your bottles. Just don’t cut any corners on sanitation next time around. These things can be defeated!
