If you have an existing Wordpress or Ghost blog, you can import your content into DynaBlogger easily.

All you need to do is export your content to a .xml file for Wordpress, or .json for Ghost, then head to the Tools page in DynaBlogger and upload the file.

The process may take some time if you're importing a lot of content. 

Images are also imported, and formatting/styling is preserved as much as possible. However, there may be some differences in the appearance of your content with DynaBlogger due to themes being different.
