Exporting data from Tag Historian

[Isabela_Babcock]

Hello!

I'm looking to migrate about 500GB of Tag Historian data from Ignition to Canary Historian. I reached out to the vendor for guidance and they asked for the different export options available by Ignition.

The only information I found in the Ignition manual points to a CSV export as the only alternative: Export Tag Historian to CSV

Given the amount of data to be transferred, CSV wouldn't be feasible it seems. Has anyone dealt with this before and could provide guidance on the options available for exporting large amounts of Tag Historian data out of Ignition? This would be a one-time transfer so the old data can go into the new historian data source, which will be Canary Historian.

Thanks in advance!

Transfer to another historian would naturally need everything to be retrieved in "As Stored" format.
