Honestly guys most if not all the stuff from the old forum have been migrated here so even if you are keeping it for research sake just know all of the stuff you want to find on there is also here now.

Personally I've kept my app too but just because I've been on it since becoming a Mi fan and it is a little hard to let it go lol. I still find myself going to the website every now and then just to check out the old format of things.
