PI Servers with Different Scan Rates using Same Tags

We are going to be implementing data retention. Our plan is to have 2 PI servers at each site, one 'high resolution' and another for 'general view' of data. The 'high resolution' PI server will be on the process control network collecting every 1 second for incident investigations, operator trending, etc., with data retention of 1 year. The 'general view' PI server will be on the IT network collecting every 1 minute with data retention of infinite. Is this a case for PItoPI writing the 1 second data to the 1 minute PI server? I don't know of any other way to do this using the same tags. Today we have the 2 PI servers as HA, one on the Process Control Network and one on IT network but the same data is written to both using nWay buffering. Is there a standard way of accomplishing what I have described? Am I on the right track by using PItoPI interface from the 'high resolution' to the 'general view' PI servers?
