I am in the process of upgrading from 2.6.11 to 3.0.5. During the initial verificatin stage, I see the Database Storage Engine no longer supported message. When I log into mysql and perform the show engines command I see the following;
mysql> SHOW ENGINES;

Within the details above it shows INNODB as Default but I still get the Storage Engine not supported.
