Migration Migraines presentation from Joomla Day Boston on March 16, 2013. I presented a Joomla migration case study for a higher education website originally based in the 1.5.x series and powered by the popular CCK extension K2. From beginning to end, the migration process to the Joomla 2.5.x series took more than 18 months. I highlighted the planning phases, troubles with migration tools, considerations of the daunting task of a manual rebuild, and the overall hybrid approach that was taken to accomplish the migration objectives.
