yeah, what used to be a pain in the ass (because it's tedious) can be offloaded now. I'd still say a lot of companies won't bother because if it's working, why update it? (sure, security, but if those instances aren't facing the internet there's low risk).

At least during the last 2 years time and time again we can read articles about how large Mainframe Migrations still keep failing.

The amount of success stories is very small.
