Marshmallow Migration

[L_Spilker]

Phone has been really buggy and I think it's time for a clean start. I'm assuming that if I backup my apps on kies I can reinstall them on the clean platform right? What if I do a clean marshmallow install, will I be able to still recover backup that was made using lollipop? I plan to remove my sd card for the whole process then remount once mm is installed and hope the os reads the card without issues. I'm literally sitting in front of my laptop waiting to do this so I would appreciate some help. I got nothing on XDA
