Methods to upgrade PHP agent (Linux/Windows)

PHP agent can be upgraded in 2 ways:

• Auto upgrade
• Manual upgrade
  

Auto upgrade:

• When this feature is enabled, the latest version of the agent is automatically downloaded and deployed when it is made available
• After the deployment process is complete, you will be requested to restart your application server. Once the server is restarted the updated version will come into effect
• To enable this feature, go to your APM Insight application > Edit option > Edit APM Agent Configuration Profile > Enable Agent Auto-Upgrade.

Note: Auto upgrade feature will only work for major version changes in agent. Minor changes will not be covered in this.

Manual upgrade:

• By default, auto-upgrade option is disabled. When a new version of the agent is available, users will be notified in the APM Instance view.
  
  

• Users can initiate the upgrade process by clicking on Update Agent link in the above said notification. On doing so, the latest version will be downloaded and deployed
• After the deployment process is complete, you will be requested to restart your application server. Once the server is restarted, the updated version will take effect
  

Note: For Windows agent, the manual restart is not required.
