Softaculous gives you an option to restore your site from other domain.After installing Oxwall on the desired domain search for restore button in softaculous. Restore site content from a different domain.
 I tested my site on a sub-domain and later restored its content on main domain.
There would be another options too but it seems easier you can move your content with a single click.

i looked softaculous restore menu there is no such a thing... can you write step by step?

I am sorry It is Import button ,
1.Go to softaculous home
2.Search for Oxwall script
3. Now you will see the options


Click On Import button.. select the domain, You are done.

there is no different domain options just under in a domain... i ask for different domain for reseller host... or how can i do manual move to different domain?

Omer, first of all are you just changing domain names only OR you are changing your servers as well?

1. If you are just changing the domain name: change the URL in config.php
2. In you Domain Management area change DNS records

in reseller server for different domain... how can i move? or if i a new setup how uprade old db to new db and images... and where is te config.php

Omer, 

If I understood you correctly, you want to transfer your current website to a new reseller hosting server with a new domain name. 

If it is so, you'll need to backup your current website and data with the Cpanel tools on your current server, then you need to to take that backup, download it from the current server, upload it to the new reseller server and upload it to the new hosting server using the CPanel tools. 

I had backup an OXwall using Oxwall script in Old server and I want to restore this backup into a new server. Please help what the step restore into new server.

Thanks

just you need to extract zip file under new server public_html directory
then you need to edit config.php under /includes if changed you db and db username

firstly you must do upload db backup to new server (you can do phpmyadmin import)
