total greenfield, gather requirements, work out what the customer wants, define the functionality of existing system, consider architecture etc? could take months, current staff is 2 burnt out jr devs

This is a black box that is generating $10k a day

Rewrite from scratch assumes you have good devs that know what needs to be built, can't even start looking under the hood of this right now. More interested in this from an ops perspective / management. Any guides / books / war stories about this sort of thing

For $10k a day, you can hire a lot better than two burnt out junior devs. If you want that money to keep flowing, plow some back in into getting several more senior people on it.

in the OP they mention they already have some much more senior devs looking at it and their big idea is to move it to Azure. [?]
