Transfer From Subdomain To Tld

[web_designer 7]

hi, again, i decided to bother you again about my domain issue. :angel: ok, now i bought a TLD domain from xisto, that means the same company for my hosting here, my domain is ready and active and i decided to transfer my whole websites to it instead of parking it or addon it because i don't want to have two sites io update everytime and it is bad for seo. so plaease steps will be these- backup my website database in my cpanal and uploaded again to my new domain. then, should i move the whole root folder or only the database.- i should update links in my new website or it will not be affected because i am the same company.- to cancel the last hosting plan i should submit a ticket to xisto, right. but what is the next step i should register a new plan giving my domain name or they will support me that or what?i need these answers to clear my mind and not being stuck in the middle, as i always do. thanks in advance.
