EEv4 - Domain Change - Best Way?

Hey guys, i need help.

I started to use easyengine to build websites for my clients, but i have found alot of trouble when trying to change the domain name.
Is there anyway to update the domain name entirely, without using plugins? or changing files?

Like site name update? Or something liked

If not, please tell me how, please!

I don’t want to migrate from server, since i’m gonna take care of hosting i’m just wanna be able to change from to his domain name.
