Originally, the initial setup was fine. It was fun. However, now it is harder. It's not getting updated. Not much is changing on it. Likely no one will be installing it anymore. I was involved in this World implementation way back. It wasn't difficult. Basically, they would give you a task, and then you go through the task. It was fun then. Now, you have to always remember a lot of commands to be able to use it, and nobody does that now. It is not difficult to maintain. If you know what you're doing, it's okay. Obviously, the IBM box is where there will be challenges. When your hardware goes off, then you have to find people with that skill set to come in and deploy for you.
