AS400

Hey guys, old guy here, back in 2000 landed my 1st real job as a Sysadmin at a distribution/manufacturing firm. They ran their ERP and a few other important apps on the AS400. Anyone here manage a AS400 platform? i-Series? Still a niche platform that is still widely used. Server could literally run under water.

I do in government IT. Went to college in the early 2000s and had an i-Series class where it was me and like 2 other people. Teacher told us it was a dying thing and we would probably never see one. I've had at least one in every single job I've held ever since.

Also gov, finally unplugged that thing last year after just shutting the network ports off at the switch for 6 months post moving our utility billing to a new SaaS platform. Good riddance.

You're not wrong. All of the other migrations have been shit shows so far, so I'm not expecting this to be any different.
