Just don’t let your technical debt fossilize. At the beginning seems like a good idea to invest little money in supporting legacy rather than migrating it, but for example, supporting and maintaining COBOL applications is a huge headache. Companies even pay big bucks for formation of new professionals and integrate the old solutions with modern applications is not even that easy since some of the OS are even alien to TCP/IP interfaces let alone modern programming interfaces (and there is nothing worse than an HTML interface on top of the old non ANSI terminal interface, even if you knew where the F21 used to be)
