I've got a debian server that I'll be migrating to new hardware in the next few days. I've done similar migrations in the past, and everything is pretty straightforward except moving Mysql. The past few migrations I've done a dump of my databases and imported them to Mysql and then manually created the user accounts that would access the DBs. I invariably miss one of the dozens of accounts and get some breakage.
I've always been wary of blindly importing the old user table into the new server for fear of breaking the auto generated accounts, so that's not something I've tried. Is there a simpler way to do such a migration?
