Hello,
While I'm new to freelancer and I only managed to complete several projects, I have by now a 100% completion rate for all of them. My name is Dragos and I'm a Senior System Administrator with more than seven years of working experience in the web hosting industry, experience that has been gained while working for one of the top web hosting companies from USA - California.
When it comes to the project that I'm bidding on, I will be more than happy to assist you with the data migration between the two 1and1 servers. During time, I have performed multiple similar tasks, on servers with different operating system's (Linux, Windows) and different control panel's (from environments without a control panel, to Plesk, cPanel, WebSitePanel and so on).
At the end of the data migration, we will verify together the functionality of all your websites and features on the new environment, before having the DNS changes performed at the registrar(s) of your domain(s).
If you have any questions regarding this please let me know.
Thank you,
Dragos
