Hi,
Let's migrate one domian and emials address right now. After successfully done, we will migrate all others.
I have a huge experience in Webhosting administration, so I can set up, tuning, debugging apache, Nginx, PHP-fpm, and other server software.
Working with WHM, CentosWP, Plesk, isp manager, or without any panel.
Also, I can provide MySQL server tuning, SSL installation, and many other Linux-based server services.
Thanks
