During the migration process from classic Google Sites to the new version, your content and formatting undergo a transformation designed to preserve as much of the original structure and appearance as possible. Google Sites' migration tool automatically transfers your content, including text, images, and embedded media, to the new site. However, there may be some differences in how certain elements are displayed or formatted due to the differences between the classic and new Google Sites platforms.

While most of the content is transferred seamlessly, you might notice changes in layout and design. The new Google Sites offers a more modern and streamlined interface, which can result in alterations to the positioning and appearance of certain elements. For instance, custom HTML, gadgets, and some formatting options that were available in classic Google Sites may not directly translate to the new version. You may need to manually adjust these elements to achieve the desired look and functionality on your new site.

Additionally, the migration tool attempts to replicate the overall structure and navigation of your classic site, but some adjustments may be necessary to ensure that the new site's navigation is intuitive and user-friendly. It is advisable to thoroughly review the new site after migration to make any necessary tweaks and ensure that all content is properly formatted and displayed as intended.

For detailed guidance on the migration process and tips for addressing potential formatting issues, you can refer to Google’s official Google Sites Help Center and their migration guide. These resources provide comprehensive instructions and best practices to help you navigate the transition smoothly.
