Upgrading VMware Tanzu GemFire
This topic describes how to plan a VMware Tanzu GemFire upgrade.
To upgrade an existing installation to a new version of Tanzu GemFire, follow these general steps:
- Back up your current system.
- Install the new version of the software.
- Stop your cluster using the current software.
- Restart the system using the new software.
In many cases, components running under the current version can be stopped selectively, then restarted under the new version so that the cluster as a whole remains functional during the upgrade process; this is known as a “rolling upgrade.”
In other cases, the entire system must be stopped in order to accomplish the upgrade, which will require some downtime for your system.
See Planning an Upgrade to choose the upgrade scenario that best suits your implementation and to understand the resources you will need to accomplish the upgrade. Then select the appropriate upgrade procedure for more detailed instructions that fit your specific needs.
