Supported Upgrade Paths
Supported upgrade paths are presented for the latest Feature Release (FR) and Long Term Support (LTS) CipherTrust Manager software versions. Consult the release model page for details about these release types. Release Notes for individual release versions also contain supported upgrade paths to that version, alongside any special instructions or considerations.
Upgrade path support follows some general patterns, with exceptions identified for particular cases:
You can upgrade a standalone, unclustered appliance up to three minor versions at one time.
You can upgrade cluster nodes in the cluster remove/rebuild method up to three minor versions at one time.
You can upgrade cluster nodes in the in-place online cluster upgrade up to one minor version at one time.
If you are starting at a version below 2.8.x, you must upgrade to 2.8.x before upgrading to higher versions.
If an FR minor version is released after an LTS scheduled patch, upgrade from the LTS patch to the minor version is not supported, even if the version number is sequentially higher. We indicate which LTS patches cannot upgrade to the latest FR version. As the LTS scheduled patches are more stable, upgrading from an LTS patch to an FR version which was released earlier can re-introduce bugs.
Upgrade to Latest Long Term Support Version
Upgrade procedures for latest LTS Version are included in software documentation for that version.
The supported cluster upgrade methods to LTS releases are online in-place, offline in-place, and cluster remove/rebuild.
