I've been party to dumping legacy systems and lift & shifts a few times.
Good fucking luck.
Knowing nothign about this, a project like this would take at least 2 years even if you are dropping a ton of use cases and dependencies.
Agreed (context: same legacy system work, 20 years), although given the size and scale of the tech debt involved, I'd peg it at 5 years if you had a team of 100+ COBOL developers.
10 to do it right.
Once you start dealing with databases older than SQL and languages older than C, things get funky real fast.
