We set up our PI Server in Dec 2011. Before that we had a different historian. It has been on my list for a while to try and import the data from the other historian but I haven't had the time to get to it yet. We are being asked to obtain some of that data now and I would like to get that data in PI so in addition I can shut down those old servers holding the data prior to 2011. I am currently running PI 2010 but plan to upgrade to 2012 prior to doing this. I found some documentation on the topic but have a few questions with it. Referring to the following document
Step 2 says to make sure current data is not being sent to the tag from the interface. I can't stop the current data from coming in to the system while I do the import. I need current data to keep coming in. Is there a way around this?
On step 7 it says to delete the Pt Created event. The Pt Created event should probably be in Dec 2011. So do I have to delete that event prior to importing the data?
The document doesn't talk about creating archive files, but my first archive file has a start date of Dec 2011. Prior to doing this, do I need to make archive files with start/end dates before that? Should I make for example, one archive file for each month that I plan to import? Is there a quick way to make archive files, I will be importing multiple years of data?
Once everything is set up I plan to write a .Net program using PI OLEDB to insert the data.
