Pierre Far and Zineb Ait Bahajji, Google Webmaster Trends Analysts had posted on the Google Webmaster blog on June 6th 2014, that they updated the official guidelines documentation for moving website.
They states that, Site moving process have to be done based on the following two ways:
- Moving the website with no URL changes
- Moving the website with URL changes
NO URL CHANGES
If you want to upgrade your website to the new platform, you have to move the website to the same domain name and same old urls. If you are going to a new hosting provider for your website then keep your old URLs unchanged.
URL CHANGES
If you are moving site that has fully new URLs then be careful while mapping old URLs to new. Webmasters have implemented the moves correctly and follow the guided steps to done site moving successfully.
Google had updated Guidelines on moving site to help web masters in moving sites and also included the issues that might occur while moving a site.
