Hi,
i can easily migrate database form odoo 10 to odoo 12.
I have a huge experience in Webhosting administration (already 9 years), so I can do a lot of tasks: setup, tuning, debugging apache, Nginx, php-fpm, and another server software.
Working with WHM, CentosWP, Plesk, ispmanager or without any panel.
Also, I can provide speedup service. mysql server tuning, SSL installation, and many other linux-based server services.
Thanks
