You can upgrade an On-Premise Poller directly from the Site24x7 web console by navigating to Admin > On-Premise Poller, clicking the hamburger icon  beside an On-Premise Poller, and clicking Upgrade. Learn more. 

As per our latest announcement, the 32-bit On-Premise Poller is no longer supported from version 6.5 and above.

Windows upgrade

1. Download the appropriate package for your architecture:
   
1. 64-bit version | 32-bit version
   
2. Locate the downloaded zip package and move the zip file to the installation directory
   
1. By default: C:\Program Files(x86)\Site24x7OnPremisePoller
   
3. Stop the On-Premise Poller.
1. Go to Start > Settings > Control Panel > Administrative tools > Services.
   
2. Alternatively, use services.msc from Run.
   
3. Stop the service named Site24x7 On-Premise Poller using administrator privileges.
   
4. Verify service status in the Services menu and check if the service has stopped.
5. Backup the entire Site24x7OnPremisePoller directory before proceeding.
1. Default directory: C:\Program Files(x86)\Site24x7OnPremisePoller
   
6. Extract the zip file into the root of the installation directory. Overwrite the existing files, if prompted.
7. After extraction, find the logs directory:
1. If logs.old directory exists, move the logs directory into logs.old directory.
   
2. If logs.old directory does not exist, rename the logs directory to logs.old.
   This ensures that only the new version's logs are present in the logs directory.
3. (Optional) Similarly, move or rename the reports directory in the same way as the logs directory. However, doing this will delete any monitoring data that hasn't yet been sent to Site24x7 servers.
   
8. Change the JRE (Java Runtime Environment)
   

This step is optional and required only when upgrading from an older version. For example, from version 11.0.23 to 11.0.26. 

1. Rename jre to jreold.
2. Rename jre_latest to jre.
9. Restart the On-Premise Poller
   
1. Use services.msc to start the Site24x7 On-Premise Poller service.
   
10.  Verify the upgrade
1. Navigate to Admin > On-Premise Poller to confirm the upgrade. Check the version number beside the On-Premise Poller name. 
   

Linux upgrade

1. Download the appropriate package for your architecture:

2. Locate the downloaded zip package and execute the command below:
   
   sudo mv <Linux zip file> /opt/Site24x7OnPremisePoller/
   

<Linux zip file>: Replace the appropriate 64-bit version in the terminal. 

1. If logs.old directory exists, move the logs directory into logs.old directory.

   This ensures that only the new version's logs are present in the logs directory.
