Using PI 2 PI History Recovery to backfill entire archives.

We are proposing to introduce a new PI Historian on the Business Domain hosted on a DMZ.

There is an existing PI Historian on the Controls network and the time series data will be PUSHED across the firewall using PI to PI Interface.


I am wondering if it is possible to copy the existing archives from the Controls PI Historian to the Business PI Historian and change the Point Source and other attributes to save time backfilling about 10 years worth of data.


The other options is to use History Recovery with Time Range parameter to backfill the data. I suspect this will take longer than copying the archive and updating the tag attributes.


My questions are:


Are they both valid method for backfilling data on to a new PI Historian?


Thank you in advance.
