As already indicated by Google, the final deadline for the migration of Destination URL to Final URLs is July 1st, 2015. On this very date, Destination URLs will be depreciated and will be replaced by Final URLs. If your URLs have tracking information attached to them at the moment, they would be moved to Tracking Template field. But, if you are using advanced tracking, you may be in trouble if you do not upgrade manually.
July 1st will be the forced upgrade. Make sure you do not have to lose your tracking in the automatic migration.
Meanwhile, Google has also launched an Upgrade Tool to help you upgrade your URLs. You can access the tool here – Upgraded URL Builder
