I copied the data directory of 5.4.2 to the data directory of 5.5.1. Upon starting mysqld of 5.5.1, I saw this error: 100122 10:13:09 [Note] Plugin 'FEDERATED' is disabled. InnoDB: The InnoDB memory heap is disabled InnoDB: Mutexes and rw_locks use Windows interlocked functions InnoDB: Error: log file .\ib_logfile0 is of different size 0 134217728 bytes InnoDB: than specified in the .cnf file 0 5242880 bytes! 100122 10:13:09 [ERROR] Plugin 'InnoDB' init function returned error. 100122 10:13:09 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. What is the recommended way of moving InnoDB data from a 5.4.2 installation to a 5.5.1 installation? Thanks -Zardosht
