Tech Note 81: How to change Wonderware Historian’s server name for Wonderware QI Analyst 4.2 workspaces and data tables

Wonderware QI Analyst can be configured to retrieve historical data from Wonderware Historian Server (formerly known as IndustrialSQL Server or InSQL). If Wonderware Historian is moved to a different computer after QI Analyst has been configured, QI Analyst may not be able to retrieve data from the Historian as an incorrect computer name or server alias is used by QI Analyst to access data. In such case Wonderware QI Analyst workspace may fail to open. This tech note describes the procedure to rectify the problem.
