On win32, I was attempting to move my InnoDB files from a 5.4.2
installation to a 5.5.1 installation. 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?
