Turn Root Site Collection into Communication Site
Not out of the box, but I found this post online that makes it look like there is a hacky way to do it (that I probably still wouldn't do): https://hangconsult.com/2017/06/29/change-sharepoint-online-root-site-collection-to-use-the-new-communication-site-template/. It seems like this would introduce some risk to your "go forward" architecture. I feel like it would be better to create a Comm Site that you use as your "home" site and then see where things shake out with concepts like enterprise news publishing. I'd hate to hack my way in to an architectural decision and then learn later on that it locks me out of future capabilities.
What if you cannot delete the root? I have a classic root that is gov't controlled so how do I do a redirect to a communication site that is instant? No client side script I have found will do that and the meta tags are laggards. I have a Powershell I need to try and run as well:
