So we upgraded out Factory talk historian and had parallel running historians. We'll call the A(old) and B(new).
Historian A has been running and collecting data, Historian B has been up and running for about 7 months.
Historian B has had new devices added to it and has been collecting data on them.
Is there any way to take the archives for the last 7 months from both systems A and B and merge them to an archive that will be mounted on B? Keeping data for all points from both systems? I am able to use the binary conversion file to covert the A archives and make them mountable on B but when I try and add them to the archives from B it doesn't seem to work.
Edit: I think I might need to reprocess the B archives once I've added the points from the A historian, then use piarchss to combine them? I'm currently trying that method.
