Follow this chart when planning your Cora SeQuence upgrade.
This article relates to the database upgrade only.
Cora SeQuence V9 applications are immutable and cannot be upgraded. Each application deployment overwrites the previous one. You only need to deploy the applications based on the database version.
- Pre-deployment actions: You need to perform specific tasks before upgrading your database. These tasks can be running SQL scripts or performing manual actions.
For example, before upgrading the database to V9.x, you need to do some cleanup.
- Post-deployment actions: You need to perform additional tasks after deploying the database. These tasks are not mandatory for the current version, but need to be executed before upgrading to the next version.
For example, some Email Listener's tables changed in V9.3. V9.3 systems can work with the previous tables or the changed ones, but V9.4 systems will work only with the changed tables.
Unless stated otherwise, when you deploy a minor version, consider the upgrade path relevant to its major version. For example, to deploy V9.4.1 consider the pre and post-deployment actions relevant for V9.4.
You can upgrade from V9.3 to V9.4 even if V9.5 is already available, but you still need to perform V9.3 post-deployment actions.
