All,
I've currently got a project to migrate a LARGE (3.5TB) MySQL data set from a Sun SPARC machine to a Sun x86 machine, both running Solaris 10 (though obviously one is x86 and the other is SPARC). Is it possible to simply copy the data files from one host to the other or is a full mysqldump/ import
necessary to preserve data integrity?


I have done straight data directory copy from server to server before (granted they were both SPARC machines) and had no problem. Off-hand, I can't think of any reason why it wouldn't work between SPARC & x86, both running the same Solaris version, especially if they're both running the same version of mySQL.

I would suggest doing a test copy, if possible to see what happens.
