Older calibration platforms can remain useful for years, but support challenges often appear slowly. Updates become harder to find, experienced users move on, and newer instruments may not fit the existing setup as easily. For laboratories that depend on stable procedures and reliable records, waiting until a system fails can create pressure. A planned change gives teams time to review data, users, and technical needs. In this article, we will discuss how laboratories can prepare for a safer move away from aging calibration systems.
