Changes in the workplace happen all the time! The key here is sharing that you are supportive of change and happily adapt to the changes. Think back to a major change that you happily welcomed in the past two years. Describe the change to the interviewer, outlining the previous process, the requested change, and your reaction to the change. Next, share that you recognized why the company was making this change, and tell the interviewer that you were excited about the change and welcomed it openly.

"I think most people would find major changes to routine procedures they conduct on a daily basis to be somewhat annoying. To be completely honest, I'd initially be a little bit annoyed, like most people. But then, I remind myself that these decisions are made in what upper management believes to be best for the company. And since I'm a team player, and I recognize that the company's best interests are also my own best interests, I just look for ways to learn the new procedures as quickly as I can. The change is going to happen anyway, so I may as well make the transition as smooth as possible.
Last year, the management at my previous company decided to upgrade the system tenants used to report maintenance issues. The current system was easy to navigate, and I had a lot of information saved on that system from previous situations I had dealt with. Ultimately, I knew the upgraded system would provide a better, more timely service for the tenants, so I quickly adjusted to the new system and even committed to training other employees on how to manage work orders that came through."
