2.1.3 to 2.1.7, but how?

[THE EXO]

Hello guys, I'm new here.
I have a question for you. My XenForo version is 2.1.3 and I want to upgrade to version 2.1.7 using the files here. But my current XenForo files are a bit problematic, so I want to update them with clean files here. How am I going to do this? How should I get a backup? Please guide me.

Thank you! ?

Hi @THE EXO
You would need to login to your hosting providers panel or FTP in to your files and either make a backup using the inbuilt tools of your providers panel or copy all the files using FTP to you PC somewhere, also make sure to take a backup of your MySQL database from the panel as well.
Once you have a backup, upload the upgrade files once uploaded then navigate to https://yoursite.tld/install and follow the instructions.
