Good day! I answer exactly my own question! You can update firmware from stable to weekly without doing any wipes or removing anything from the device! Tested on Mi 8 SE and MIUI.EU firmware.

Hello, friends! I use Mi 8 SE on a stable version of MIUI.EU, but I want to switch to the weekly version. My question is: Can I do this without deleting any files from the phone and not doing wipe and system demolition?
