Upgrade Rom To Nougat - Is That Fresh Install?

[Maziak]

Guys, do I understand correctly that while upgrading to Nougat (from Android v6 to v7) I will have clean installation and I'll have to reinstall all my apps?
Is there a way, how to do backup of apps, settings, etc. so I have it restored after upgrade? Or is that manual, one by one app install again?

Thanks for help
J.

In settings > more settings > factory reset
U have an option to backup all your apps with data to internal memory...
After it's finished, backup folder in your PC...

Other way, use titanium backup 8.x.x minimum !!

Flash new romm with clean install, and restore using previous method used !

Cheers
