[ISS Support Case] Historian Server Upgrade Questions
Last updated: March 7th, 2025Description
Almost ready to replace an old Wonderware 2014 Historian with a new Historian running System Platform 2020 R2 SP1 on a Windows 2019 VM. The new SP Historian server has been running for the past couple of months and collecting data. Would like to copy all history blocks from the 2014 Historian to the new Historian. Should I delete all history block folders on the new Historian and copy over all history block folders from the old Historian or do I only need to copy over the history block folders that do not currently exist on the new Historian? Need to make sure that we are keeping all of our historical data intact. Have been following https://3777554.extforms.netsuite.com/app/site/crm/externalcasepage.nl/compid.3777554/.f?formid=6&h=AACffht_vbqCKdcsKDfLP4IS_S5lgzIuuAQ&redirect_count=1&did_javascript_redirect=T as a guide. Also, have one Historian Enterprise 25K Tag license and one Historian Local 25K Tag license for a Backup Historian. After retirement of our old Historian and conversion to the new Historian, I will be standing up the Backup Local Historian. Since the Historian software will be exactly the same on the Backup Local History as on the primary Historian, will the Backup Local Historian know to use the available Historian Local 25K Tag license?
