If you find that you need to switch the operating system of your hosting account, you can do so at any time.
NOTE: You cannot switch the operating system of a hosting account created using a free credit, with a secure socket layer (SSL) installed on it, or if it has an active mobile site.
NOTE: If you do not see the Plan menu, contact customer support.
This change might take up to 72 hours depending on the size of the site, the number of databases and other factors that may increase the complexity of the migration. We recommend that you do not try to FTP to your hosting account during the migration. You will receive an email message when we complete your upgrade.
NOTE: If your website contains certain advanced features, such as ASP, ASP.NET, CGI, or PHP applications and you select a hosting plan that does not support those advanced features, your website may no longer function properly after the plan change. Please make sure your website does not contain advanced features BEFORE moving to a plan that may not support them or be prepared to modify your Web content accordingly.
NOTE: If you created databases that are incompatible with the new operating system, you must delete them before proceeding. Data existing in compatible databases will be preserved.
