# How do I upgrade a meter from NHH to HH?

Under MHHS, you don’t physically “upgrade” a meter from Non-Half Hourly (NHH) to Half-Hourly (HH). Instead, MHHS re-categorises meters into **Advanced, Smart, or UMS (Unmetered Supply)** segments, and those categories determine whether a meter is settled half-hourly.

In future, we plan to add a new **MHHS Market Segment** field alongside the existing **MHHS – Migration Complete** flag to make settlement status clear. We’ll time this update with the first live migrations so it reflects how the process works in practice.
