Upgrading CTE agent in an LDT Communication Group
Upgrading from 7.2.0. to 7.3.0
Upgrading to 7.4.0
You can Upgrade CTE from previous versions to 7.4.0 with no special considerations.
Warning
For CTE Agents using LDT over CFS/NFS, you MUST upgrade to v7.4.0 BEFORE you can upgrade to 7.5.0. You cannot upgrade to 7.5.0 from versions previous to 7.4.0.
Upgrading to 7.5.0 and Post 7.5.0
Note
CipherTrust Transparent Encryption 7.5.0, and subsequent versions, have architectural design changes which require all nodes, Windows and Linux, to run CTE 7.5.0 in order for the LDT Communication Group nodes to communicate properly. The architecture design changes introduces New Terminologies. It is critical to understand these new terms.
Best Practices for Upgrading
Only perform an upgrade when LDT is NOT in progress or is in a SUSPENDED state.
Triad Nodes
- Upgrade the LDT Communication Group replica nodes one at a time, before upgrading the LDT Communication Group primary node. When the LDT Communication Group primary is upgraded, the primary fails over to one of the secondary nodes, which becomes the new primary node.
LDT GuardPoint Group
- Upgrade the secondary nodes first, followed by the primary node.
To check the current node role and status of the LDT Communication Group, type:
voradmin ldt group list <guard path>
