RE: OS400 DATA MIGRATION

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

I was speaking of cheaper in the sense of lost time, risk of lost data if
the machine dies while running unprotected, risk of lost data if one of the
backup tapes decides to be unreadable - that kind of cheaper.

In my opinion, people sometimes spend too much time worrying about hardware
cost.  How much would the expansion unit cost and what feature/function
would he get for it?  (that's a real question, not rhetorical)  How much
will a decent developer cost for the next year?  I would guess about
$100,000 with desk, floor space, phone, PC, wages, overhead, machine cycles
to support him, parking spot, and so forth.  How much will it cost to
rebuild the world if the backup turns out to be unreadable?  How much will
it cost in hours for the OP to fix if that happens?  How much will it cost
the business in lost opportunity while their people cannot use the system?

Hardware-corner-cutting is no more cost effective today than it was 30 years
ago.  We have to work harder to defend it because people will point to a
$3,000 PC.  I ask, "Is the PC the same as a 400?  Does it do the same stuff
and work as reliably?"  If not, then it doesn't matter.
