So the temp site 'info/xyz' is a subdomain of main domain? If you expire main domain 'info/xyz' will go into the void..... disappear, as it is dependant on the IP address of main domain! I would make full backups or pay for main domain.
Any subdomain (child) is dependant on it's main domain (parent). You can't access it without the IP address of the parent domain.
So if you are using a trial for example and you let the trial expire, the only way you can save your subdomain is to make backups and then register a new domain, get hosting, upload saved files. Also they type of files will dictate future hosting choices. Gocentral will need Gocentral, Wordpress will need Wordpress.
