Dawna Olsen presented on her experience leading a complex modern web migration project for Epicor Software that involved migrating 17 global sites from SharePoint to a new content management system. The project required maintaining current sites, implementing responsive design, migrating content, and managing over 5,500 redirects. It faced challenges such as application instability, limited resources, and the loss of content during an upgrade. Through extensive planning, testing, and fast action after launch, the new sites were able to recover search traffic within three weeks.
