2Migration – Migration Analysis & Plan



2Out-of-Box Solution (Ecometry, etc.)

Complete code replacement

Code Emulation (AMXW)

Remain on MPE (All, partial, attrition)

Some combination of all of the above

Migration – Migration Analysis & Plan



2• What to do, what to do (with the application)?• The Five Choices

1) Retire Who needs it!2) Maintain Keep it on the 3000!3) Rewrite Create your own replacement.4) Replace We never liked it anyway.5) Migrate We need it.

Memory 2 to 5 MB / user

Unix/ NT CPU size 1.3 to 1.5 x HP3000 CPU<<NB Unix equivalents of MPE boxes are much less expensive>>

Wide area network Wingspan works in character mode (X25 and Frame Relay tuning)

Mathematical models to predict the actual response time
