FS Collection deprecated

Hi Guys,
I am really shocked now. I am using FSCollection and GRIDFS FileSystem. I invested loads of time and now It turns out FSCollection is deprecated? Can someone please advise me what to do now. I mean I am 5 mins before a launch. Oh no!

I’m afraid of this as well, I think we all need this kind of approach, and CollectionFS was fine answer.
If there was a problem and a way to solve, please someone shares that point.
