Migration Process
Introduction
As part of this OS migration project, 4 major activities should be considered and planned for:
Creation and configuration of the new TrendMiner server
Upgrade of the existing TrendMiner server to 2024.R2.0
Migration of application data from the existing server to the new server
The project and change management to have a seamless user transition
In the following sections, each activity will be covered.
High-level Process
The migration process consists of several steps that should be executed in order. The following overview describes this process step-by-step:
Creation of a new TrendMiner server based on one of the new underlying OS deployment options ("target system") and installation of TrendMiner version 2024.R2.0.
Configuration of this target system
Communicate a "freeze date" to the user community: any work created after this date on the source system won't be part of the migration
Upgrade the existing TrendMiner server ("source system') to TrendMiner version 2024.R2.0
Upgrade the Plant Integrations module to the latest version
On the freeze date: Creation of a backup on the source system
As soon as the backup is finished, restore it to the target system
Re-configuration of some elements on the target system
Validation of the target system by administrators/key users
Communicate successful migration to the user community
Turn off the source system
It is recommended to take server snapshots before any major activity, e.g. a snapshot of the source system before it is upgraded to 2024.R2.0, or a snapshot of the target system after the configuration but before the backup restore.
