This dialog allows you to import data from Advanced Web Ranking projects created with version 4.1 or lower. You can access this dialog via the Project -> Import AWR Projects menu.

Since Advanced Web Ranking 4.5, the database format has been changed to an SQL relational database. This is a faster and more scalable database but is incompatible with the old format. Therefore, your old projects need to be converted to the new format before using them.
To ensure the safety of your data during the conversion, a new data folder has been created which contains only the "news" demo project. Your old data folder will only be used to import your existing projects as a read only resource. Once the import process is done, you can safely remove the old data folder.
All you need to do now is select the projects you wish to convert and click the Import button.
If your projects reside on a different location, just click on the [Browse...] button and select the folder where your data folder resides. You will be presented with list of all the projects found in that folder.
