Before You Upgrade

This section provides information you need to know before you begin to upgrade Pivotal GemFire.

  • Rolling upgrades are not supported for transitioning to Gemfire 9.0. Therefore, it is important to note that downtime will be required for an in-place upgrade of each individual GemFire cluster. Downtime should be scheduled accordingly to reduce complications to business function.
  • Know how to configure environment variables for your system. See Configuring and Running a Cluster.
  • Confirm that your system meets the requirements to run GemFire. See Supported Configurations and System Requirements.
