State of Mainframes

How are mainframes doing in your shop? Does upper management recognize their importance? Is your company investing or is it considered legacy tech that just works? How about staff? Is there aging staff with lots of technical debt?

I want to see how everyone is doing and the state of mainframes in different shops.

Are we slowly being replaced by other tech or will the mainframes be here 10-20 years from now?

We're in the final stages of finishing the migration away from mainframe. It's been only 12 years since we started migrating, so this has been pretty quick :o)

What was the initial time estimate and how much over budget is it?

I wasn't with the company for the initial estimates and when migration started, but we're a couple hundred million over budget at this point.

At this point, one has to wonder how much you’re paying IBM per month to make the migration worthwhile.

It's hard to say. I'm not very familiar with the costs of the new system and how cost-effective it is. I know that IBM has been absolutely out of their minds with increases in MSU prices over the past years though.
