Duplicate Existing Magento 2 Website and Database to Create Dev Site on Different Domain, Same Server, Also SSL Certificate required so we can test payment gateway which is very important as we will doing further development and testing on gateway.
Need to be familiar with 1&1 Power Deal Server L4i, Plesk, 1&1 Control Panel, Creating SSL Certificate
Duplicate this site: [url removed, login to view]
put duplicate here to: [url removed, login to view]
SSL Certificate needs to be setup ( can use 1&1 control panel )
Make sure site is in complete working order so it works the same as original but on new domain.
