Home Server Relocating

I started self hosting with a home server last year, and had put it in a room in the house where there was an ethernet port.

Last week, me and my dad wired up the house with ethernet ports and a switch and now I want to move my home server from it's current location to a different room in the house.

Is there any sort of guidance or guide about how to properly move a server? I don't want to mess up my server since it is a repurposed old desktop. I also run Yunohost on it if that's important to know.
