[ISS Support Case] Historian not showing new data after shutdown/enable

Last updated: March 7th, 2025

Description

I shutdown/disabled Historian, deleted some one data in Circular, and allowed Historian to run again. I'm not getting any new data showing, though acquisition is showing new data being collected. All of the old data is still there. I tried deleting index-history.dat from \Historian\Data\DataIndex and having it regenerate and I tried dropping new Taginfo.dat and Taginfo-tagid.idx into an existing cyclical subfolder, to no avail :(
