Embodiments include methods and systems of site migration. In one embodiment, a site migrator receives a website address from a user for a website to be migrated to a content management system (CMS). The site migrator accesses source code of the website at the received website address. The site migrator identifies markup content of the website based on source code of the website. The markup content includes tags grouping content of the website. The site migrator transforms the identified markup content into content modules in a format usable by the CMS based on the tags grouping the content of the website. The site migrator stores the content modules to a memory, sends the content modules to the CMS via an application programming interface (API) to generate a second website which resembles the website to be migrated based on the content modules.
