The UMD Blackboard to Canvas Migration Team debriefed on their four phase process to migrate over 23,000 course spaces from Blackboard to Canvas. Phase 1 involved planning and needs analysis from December 2011 to February 2012. Phase 2 finalized migration strategies and timelines from June to July 2012. Phase 3 migrated all courses in phases based on terms from July 2012 to March 2013. Phase 4, currently in progress, addresses lingering issues and supports faculty rebuilding efforts from October 2012 to June 2013. Key lessons learned included allowing ample migration time, solid communication, phased migration, and ensuring ongoing support for faculty.
