You are correct in your suspicion. You cannot simply move archive files between PI Data Archive servers (A and B) except for 2 conditions:
1. The two PI Data Archive servers (A and B) are both members of the same (in sync) PI Data Archive HA Collective
2. You moved and registered the archives from A to B immediately after restoring B from a backup of A (this is done most often when performing a move of a PI DA server)
When PI APS creates the points on the new server, it will create the points, but this does not guarantee these points all share identical pointid/recno configuration. You can likely get at least 48 hours of history because this was backfilled by PItoPI. In order to get all history, a different approach will be needed.
You can remove all historical archives from the B server (that were copied from A) and use PI SMT to create new, blank archives for backfilling. Then, the simplest solution would just be to further utilize PItoPI to backfill the history necessary.
This said, what is the purpose of the new PI Data Archive "B"? Is this meant to be a test environment? or something else?
Adam, thank you. The B archive is meant as a replica in the cloud for an internal test system, where other applications are analyzing/using the test data. Also as a backup improvement.
I will try adding empty archives for backfilling, and test it with a month or two of data as history recovery in PI to PI then.
