Would like to use Powershell to manage the process of update/create of tags in our two development PI historians. We already use PI to PI to assure these environments have accurate data, but it can be daunting to always update tags when our production PI historian changes. I do have the process on how to build piconfig batch files and have done this in the past to export out tag data. However, it has been a while since i have written a PS script that would pass in the current date and do a differential query to PI prod and export the list only to evaluate the PI dev environment and make changes as required. Might there be examples or downloads I could reference to get an idea of the direction I should head in builing this tool?
