Never know quite how to describe this 'migration' - it's the same old bits in the machine but I've built a new installation of FreeBSD onto a new HDD and am now putting this new 'server' (hdd!) into the old machine! Sounds pretty weak/easy maybe but it's taken me almost a month to get this done what with migrating various bits and bobs and tidying up crap along the way - together with a heavy dose of procrastination along with it all. Just managed to whittle the MySQL dbs down to about 25% of what they used to be, so many dbs and users that haven't used anything since 2003 or so!
Mind, not that it's active that much now, we're talking maybe a dozen users or so...
Anyway, still got a lot to do, the server is just about running now with the new HDD, managed to get named up and running along with apache, exim and mysql with all the data more or less migrated over now. There *will* be lots of problems with web services but that can wait for now, nothing that can't wait til tomorrow.
