alt Hacker NewsI find that highly unlikely given how much commercial agreements with MS costs.
But if that's the case then they should either look for a different COTS solution, and/or change their business workflow.
And in the event even that is unfeasible, then just continue to keep a few windows machines (maybe convert them to VMs or VDIs for ease of maintenance) for the few users that can't be migrated.
Have you, personally, ever had to convert an MS Access based application that took years to write to something else? It seems like all your responses either shift responsibility or hand wave it away. I'm sure migration is incredibly easy when you don't have to deal with said migration in a meaningful way.
