I have a bunch of product sites built on wordpress 4.7 and recently moved them to a multisite install for easier management. I'd be willing to see if I can move all this to Godaddy so I won't have to deal with the operating system upgrades/updates, database and all the other stuff.
About the sites: Nothing fancy or custom, just standard wordpress blogs with random themes (most complex would be Divi) and a few plugins. For example: Sports book software.com
Also can I do any modifications I want on themes/plugin source files?
