Allows Confluence spaces to be copied within the same Confluence instance
Copy Space allows a space administrator to copy a space, including the pages within the space, but excluding page history, blog posts and email.
This plugin is no longer supported or maintained. It is not compatible with Confluence 7.x and later, and there are currently no plans to implement compatibility with newer versions of Confluence.
See How to copy or rename a space in Confluence to find out if there's a workaround that might work for your situation.
