This machine needs to be modernized!
...seems to be the chant of the moment.
But I put it to you that it is not the Computer System that needs modernizing: It is the applications that run on the system... and more importantly the *expectations* of the users and developers that need modernizing.
Most IBM midrange systems out there have been upgraded/replaced over the last five+ years with the latest IBM hardware - IBM Power Systems. Do IBM Power Systems need upgrading?
Even if you are one of the few IBM midrange shops out there running older system architecture like the older models of IBM iSeries Server, its not that they need modernizing - because I'm sure they are humming along quite contentedly. If your old iSeries Server is running latest version IBM i operating system then does it still need upgrading?
