This reminds me of something Joel Spolsky said awhile back[1] "Never Rewrite from Scratch". I stand by that too.. even if it's a legacy mainframe app it's probably better to use strangler pattern if you really need to extend it an the development platform doesn't suit the need. I'm also reminded of the SABRE rewrite that had similar issues where agents got massively slowed down by the removal of the 10key navigation that ruled the old system and they had to add it back as emulation.
