Pointing website to another server

Hello. I have my current website http://vergedesign.co.uk pointed to my hosting.... i use this hosting for not only my website but also for development sites (for clients viewing purposes ... so things like test1.vergedesign.co.uk )

Now my question is - can i point ONLY my main domain http://vergedesign.co.uk to another server? (i will be pointing it to here http://wordpress-25386-54216-142790.cloudwaysapps.com/ ) Its the exact same website but on a different faster server.

So to conclude i dont want to move my entire domain as i still want to use sub domains for testing purposes on my current server, i just want to point the name vergedesign.co.uk to another server (with CNAME?)
