1. Stop the CMS instance application pool:
   1. Open Internet Information Services Manager (IIS) and navigate to the CMS instance application pool.
   2. Right-click the application pool and select Stop.
      The CMS instance stops running.
2. Back up your existing Web.config file from [Drive:]\[path-to-cms-site-instance]\App_Data\xml\Custom\OxygenWebService\ to preserve your current settings.
   Note

   You will merge your existing settings with the updated Web.config file in a later step.
3. Delete all contents from the existing [Drive:]\[path-to-cms-site-instance]\App_Data\xml\Custom\OxygenWebService\ folder.
   Important

   Remove all files and subfolders from the OxygenWebService directory before extracting the new package contents.
4. Extract all contents from the target OxygenWebService_[version-number].zip package to the [Drive:]\[path-to-cms-site-instance]\App_Data\xml\Custom\OxygenWebService\ folder.
   The updated Oxygen Web Service files populate the OxygenWebService folder, including a new Web.config file.
5. Merge your backed-up Web.config settings with the new Web.config file to preserve your existing configuration:
   Tip

   Compare the backed-up file with the new file to identify which settings need to be transferred. Key settings typically include user credentials, folder IDs, and custom configuration values.
   1. Open both the backed-up Web.config and the new Web.config in a text editor.
   2. Compare and copy your custom settings from the backed-up file to the corresponding locations in the new file.
   3. Save the updated Web.config file.
6. Start the CMS instance application pool:
   1. Open Internet Information Services Manager (IIS) and navigate to the CMS instance's application pool.
   2. Right-click the application pool and select Start.
      The CMS instance starts running.
