In the current version of dotCMS, Pages are another form of Content. In dotCMS versions prior to version 3.1 pages were separate from content; these previous pages are now referred to as Legacy HTML Pages. When upgrading from an older version of dotCMS, Legacy HTML Pages should be converted to Page Content. Legacy HTML Pages can be converted to Page Content by converting each page individually, or in bulk using the HTML Pages to Content Utility.
To convert ALL legacy HTML Pages to Content, select "System → Maintenance". From the Maintenance view, select the Tools tab and scroll down the page to locate the Migrate HTML Pages to Content utility.
Click the Execute button to convert all Legacy HTML Pages to Page Content.
If you have very large numbers of legacy HTML Pages, you may wish to run this bulk process during non-peak traffic hours on the server.
