Terabyte migrations with minimal downtime

April 2012 sees me at the tail-end of a few terabytes worth of data migrations for "a large government department" in Australia. The plan was to avoid significant outage due to legal requirements and public safety concerns. Enterprise Replication has been the key to the whole process; and quite a successful one at that.
Greetings keen Informix aficionados. I'm starting this blog as a gathering place for techniques and ideas, mostly so I can find them again. I used to spend a lot of time in the IIUG mailing list (under a different name) but kinda dropped out. Now I'm back in the game so it's time to start collecting thoughts... There's also a bunch of scripts and programs I want to save for posterity so they will probably hit the pages before too long.

Polite and friendly feedback is always welcome, but no obnoxious clowns please. Oh, and before I sign off, NO MIME and especially NO RAID5 NO RAID5 NO RAID5 please*

Thanks.

* a few people in the world will get the joke. Sorry if you're not one of them.
