Hello, I am very happy that you like aaPanel.
If you want to migrate your hosting website to aaPanel
First you need to have a separate clean server, it must not have any web environment installed.
Record the version of the web environment your site is currently using,
Install these in aapanel
now you can create a website with the same name as the domain name of the site you need to migrate in aaPanel.
Download the site data and database you hosted on other platforms ,imported to the site just created on aapanel and test it
Of course, you better find someone with experience in the operation and maintenance website to do this. He knows how to do it.
