Charles, I'm not sure that "Move an existing 5250 app to the web" is
much clearer.

If I have a green-screen program right now, and I rewrite it from the
ground up in a web framework, have I "moved it" to the web? I'm
guessing not -- but you could make the argument that you did, because it
was 5250, now it's web.

You have, but the tool didn't do it for you so no.

If I run a 5250 emulator whose output is a web page, i.e. where the
application program is still writing a 5250 display, and that 5250
display is being transformed on the fly ("screen scraper") is that
moving it to the web? (I'd submit not -- because the application didn't
change to be a web application -- but you might not agree.)

I'd count "screen scraping", but I'd note that that's what's being done.
But I wouldn't count a 5250 emulator screen on a web page.

What about tools that do a one-time conversion from 5250 screen to a web
page, and then you have to rewrite (or significantly modify) your RPG
program to use the resultant screen? Or rewrite in a different
language? Does that count? Does rewriting the program count as
"moving" it?

Again, If you have to manually rewrite, that doesn't count.

IMHO, if the term isn't clarified, virtually any sort of web application
can be interpreted as "Suitable for 5250 migration".
