Infor is huge in the ERP space and dates back to bigger iron days(mainframe and midrange - IBM AS/400). They acquired a lot of smaller players over the years which might be way they are somewhat unknown these days unless you date yourself to that era.
Oh huh ... I actually did a lot of AS/400 & Stratus work back in the 80s. So Infor isn't written in RPG is it? the 400 actually had a decent COBOL compiler but everything seemed to end up in RPG :-/
I'm not a young man and my dad used to talk about and work on this stuff back in the 80's-90's he's long since retired. I think your best bet here would be to train someone I can't imagine there are many folks left who worked on these systems...
Interesting(unnerving?) to see a number of domain registrars that offer their own DNS services utilize at least some kind of Cloudflare service for at least their own web fronts. Did a check on 6 registrar sites I currently interact with and half were down(Namecheap/Spaceship, Name, Dynadot) and up(Porkbun, Gandi, GoDaddy).
I just considered moving from Namecheap to Porkbun as Namecheap is down, but Porkbun use Cloudflare for their CAPTCHA meaning I'm unable to signup and I assume log in as well, so also no good.
The 16" doesn't offer the M5(yet), rather the M4 Pro and Max CPUs. Difference also is higher number of performance cores vs efficiency cores and memory bandwidth is significantly higher in the M4 lines(273 and 410 GB/s) versus the M5(153 GB/s).
