Tag Historian, retire all tags


We have a couple of thousand tags duplicated in the table “sqlth_te” with retired = null. We are thinking about to set retired = “date” to all the tags, and restarts Ignition. When this happens, Ignition will be able to create again the tags correctly? and will be able to find all the data with the retired tags in the older tables?

We use Ignition 7.9.7.

Thank you so much,
