While the Documentation theme is the recommended replacement, it is not an exact replacement. In fact, options for customizing your leftlefthand-side navigation bar is severely limited with the new theme. If you have a significant amount of customization in your existing space, we encourage you to review the documentation provided by Atlassian (e.g., vendor documentation http://confluence.atlassian.com/x/kQq6D) in order to make an informed decision about your space theme. You can change your theme at any time. |
