Applying Hotfixes to a Cold Standby Setup

The recommended way to apply hotfixes to a cold stanby setup is by installing them to the primary instance and then cloning it into a new cold standby instance with the hotfixes installed.

You can do this by following the steps outlined below:

1. Stop the synchronization process on the cold standby instance by going to the JMX Console and using the org.apache.jackrabbit.oak: Status ("Standby")bean. For more information on how to do this, see the section on Monitoring.
2. Stop the cold standby instance.
3. Install the hotfix on the primary instance. For more details on how to install a hotfix, see How to Work With Packages.
4. Test the instance for issues after the installation. 
5. Remove the cold standby instance by deleting its installation folder.
6. Stop the primary instance and clone it by performing a file system copy of its entire installation folder to the location of the cold standby.
7. Reconfigure the newly created clone to act as a cold standby instance. For additional details, see Creating an AEM TarMK Cold Standby Setup.
8. Start both the primary and the cold standby instances.
