I would actually recommend that you contact your Account Manager or Field service team as it's not an easy job to do above. Depending on your data collection frequency, 10 years of data can take a long time or not so much by today's standard.
But there can be other considerations such as PDI displays and MDB modules. Simply copying the archive files over to your corporate server will not be possible.
In order for you to see plant data along with your other corporate/plant sites data, you need to merge plant PI data into the corporate one.
Some other considerations are also described here in KB00119 - How to merge two PI Servers What issues need to be taken into consideration when merging MDB or Batches
Thanks for the response. I agree it does not seem like a trivial task.
There is no MDB data or Batch data, does this simplify the task?
PDI displays and any other consumers from the plant side will need to be revised to the new server.
Thanks for your help.
