Preparing your team for Confluence 5
Confluence 5.0 introduces a number of significant changes to the user experience: A new way of creating content, a redesigned header, a new sidebar, and other changes to the look and feel of your site. People in your organization will need to be aware of the coming changes, so that they can plan and prepare for them. We have written a guide to help you: Planning for Confluence 5.

Upgrade Process and Effects
Content updates after upgrade
You will notice once you upgrade to Confluence 5.0, every page will have been edited during the migration process. This manifests itself in the appearance of changes to every page's content by various different users. When migrating pages, Confluence will show the same username that last contributed to your content as the author of the change. This is the upgrade task of migrating your wiki page storage format to XHTML from Wiki Markup. Do not be alarmed by this. This will only happen once for all current versions of content. This will not trigger email notifications, but will update your RSS feeds. Where possible, a change comment of "Upgraded to Confluence 4" will be added to pages and blog posts.
User macros migration
After upgrading, user macros will not be able to be inserted until they have defined macro parameters. See User Macro Template Syntax. Defining macro parameters will mean that they can once again insert these user macros.
Email notifications
With the update of the email templates, the textual content of the notifications has also changed. These wording changes may invalidate any email filters set up to label or organize your email notifications.
Plain text emails no longer available
Emails are now only available in HTML format, which allows for the display of images and formatted content, such as changes made and the full content of the updated page or blog post.
