vFabric GemFire Version Compatibility Rules

This topic describes the compatibility rules for deploying different versions of vFabric GemFire.

Version Compatibility Between Peers and Cache Servers

You can have two different minor versions of GemFire running in the same distributed system cluster. For example, you can have peers or cache servers running vFabric GemFire 6.6.0 and 6.6.2 at the same time for the purposes of a rolling upgrade. You cannot run different major versions in the same distributed system cluster. See Performing a Rolling Upgrade for more details on how to upgrade your system gradually between minor versions.

Version Compatibility Between Clients and Servers

GemFire clients can run an older version of GemFire and still connect to GemFire servers running a newer version. In other words, a client running GemFire 5.7 will be able to connect to a server running GemFire 6.6.2. Newer clients, however, cannot connect to servers running older versions of GemFire.

Version Compatibility Between Sites in Multi-Site (WAN) Deployments

In multi-site (WAN) deployments, you can run different major versions of vFabric GemFire on the different sites. For example, one site can be running GemFire 5.7 and another site running GemFire 6.6.2 and the sites should still be able to communicate with one another.
