Backfeeding Data into a central Ignition gateway


Here’s an interesting thought.

The remote site has data from the past 2 years. We’re trying to spin up a central gateway (hosted on AWS or elsewhere) which will connect to the site gateway through the “Gateway Network”.
I can see the realtime tags of the ‘remote’ site from the ‘central’ gateway through the use of Remote Tag Provider.

Question is: how can I work with historizing the future data to a central db (AWS RDS) and, more importantly, backfeeding the last 2 years of data into AWS?

I think the issue might exist in the way tags are referenced by the gateway.

Any ideas?
