Hi, I have Ignition Edge running on a device that is sending data to my central server which hosts a SQL Historian. I wish to rename this historian since the name I used was a test name but I have already been collecting data from the edge device for several months now. If I rename the SQL historian (and obviously make sure that my edge device syncs to the renamed historian), would that create any metadata breaks or cause a loss of data? Would it create multiple historians that we would need to navigate within the Power Chart for example?
Yes.
Metadata is keyed to historian name, source gateway name, and source gateway tag provider name. It gets complicated fast.
You should study the published schema of the SQL historian to work out the metadata corrections you will need to end up with unbroken history. (Make good DB backups before you start.)
I would duplicate the DB and set up trial gateways to test, test, test.
