I've worked in Orgs with Cobol code written in the 70s and 80s still around. The strategy of moving your business over to a more performant / scalable tech, in essence means you now have two sets of technologies that just end up sitting on top of each other. I worked on a business line that literally had Java, Javascript, Cobol, VBScript, C#, and Smalltalk all working somewhere in the business process counting only in house written code! Businesses never actually modernize everything. They patch old code, write new stuff in new tech, and it grows in complexity. So the invest in core techs we already use is I think a great idea.
