LATEST VERSION: 9.1.0 - CHANGELOG
Pivotal GemFire® v9.1

How To Upgrade

Upgrade to the Latest Version 9 from an Earlier Version 9

If possible, follow the Rolling Upgrade procedure. A multi-site installation can also do rolling upgrades within each site. If a rolling upgrade is not possible, follow the Upgrade with Cluster Downtime procedure.

A rolling upgrade is not possible for a cluster that has partitioned regions without redundancy. Without the redundancy, region entries would be lost when individual servers were taken out of the cluster during a rolling upgrade.

Upgrade to Version 9 from Version 8.2.3 or a More Recent 8.2 Version

To upgrade all servers from version 8.2.3 or a more recent version of 8.2 to this version of Pivotal GemFire 9, follow the Windows/Unix/Linux—Upgrade from Version 8.2 to Version 9 procedure.

Upgrade to Version 9 from Version 8.2.2 or an Earlier Version

All upgrades to this Pivotal GemFire version 9 from Pivotal GemFire versions earlier than version 8.2.3 follow a two-step process:

  1. Upgrade all servers to the most recent version of Pivotal GemFire version 8.2. If possible, follow the Rolling Upgrade procedure. If a rolling upgrade is not possible, follow the Upgrade with Cluster Downtime procedure.

    A rolling upgrade is not possible for a cluster that has partitioned regions without redundancy. Without the redundancy, region entries would be lost when individual servers were taken out of the cluster during a rolling upgrade.

  2. Upgrade all servers from the most recent version of 8.2 to this version of Pivotal GemFire 9. Follow the Windows/Unix/Linux—Upgrade from Version 8.2 to Version 9 procedure.

Upgrade a Multi-Site System to Version 9 from Version 8.2.2 or an Earlier Version

Multi-site systems that have both persistent disk stores and use bidirectional WAN gateways to replicate data among sites may be able to avoid taking the entire system down to upgrade to version 9. This Multi-site Upgrade from Version 8.2 to Version 9 procedure requires multiple reconfigurations during the upgrade as one site at a time is upgraded.
