Transferring Forum from a sub-domain to another.

After i deleted the files in my sub-domain www.paulyii.epizy.com because i can’t complete my installation.
After that i uploaded another version.
But just can’t get the installation running (page not found).
So i created another sub-domain
http://www.Ban-lam-ue.epizy.com/forum.php

Now i had successfully installed the forum on the later sub-domain.

What i want to know is
Can i transfer the completed Forum to the sub-domain that is empty ?

Because i love
www.paulyii.epizy.com
more than
http://www.Ban-lam-ue.epizy.com/forum.php)

Any help will be much appreciated.
Thanks.

Of course: just move the files to the folder of the other subdomain and make sure the URL settings in your website are correct (exact instructions depend on the software you’re using).

Please do note that if the subdomain was the first domain you created the account with, and you recreated it later through the Subdomains menu, the folder is no longer htdocs but paulyii.epizy.com/htdocs.
