How To Change the Data Historian Location (version 21)

  • updated 2 yrs ago

Upon the initial install of Canary software, the user has the option of choosing where the 'Historian Data Location' will be located. By default, historical data will be stored in C:\Historian Data.

If the user wishes to change this location at a later time, the following steps must be taken.

  1. Stop the Historian service.
  2. Move the Historian Data folder to its new location.
  3. Update the 'BasePath' registry key to point to the new filepath. This is located in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Canary Labs\Historian.
  4. Open the C:\ProgramData\Canary [Labs]\Historian\Historian.ini file.
  5. Find and replace "C:\Historian Data" with the new filepath for each dataset.
  6. Start the Historian service.
