We are developing a software solution that will query PI tags stored on a PI Server 2012 hosted at the customer site. In our development environment, we have an installation of PI Server 2016. If we implement a solution that can query the tags in our dev PI Server 2016, will it also work in the customer environment with PI Server 2012? If so, what version of the SDK should we use to keep the compatibility? If not, can you recommend the best approach for us to target PI Server 2012?
