Migration Scenario's
Depending on your current setup there are a number of scenarios that can followed for doing the TrendMiner migration from CentOS to AlmaLinux.
 |
The common steps are:
Upgrade the current TrendMiner application to the 2024.R2.0 version for CentOS
Upgrade the current PlantIntegration application to the latest version
Provision a new instance according to the System requirements for AlmaLinux or RedHat 9
Install the AlmaLinux TrendMiner 2024.R2.0 application
Backup the CentOS TrendMiner application data
Restore the TrendMiner application data on the AlmaLinux instance
Below you can find the following migration scenario explained:
On-prem → On-prem with remote storage on AWS/Azure
To upgrade TrendMiner to a new On-premise instance, you can leverage remote storage on AWS or Microsoft Azure to migrate all application data.
On-prem → Private Cloud with remote storage on AWS/Azure
To upgrade TrendMiner to a new instance on your cloud provider, you can leverage remote storage on AWS or Microsoft Azure to migrate all application data.
On-prem → On-prem with using TrendMiner Backup & Import
To upgrade TrendMiner to a new On-premise instance, you can leverage the backup option in EdgeManager and upload the backup to the new instance. This will require you to rebuild all indexes for the tags.
On-prem → On-prem with remote storage on AWS/Azure
Warning
This procedure is only supported as from TrendMiner Version 2024.R2
In this scenario, the current TrendMiner application is hosted on-premises and the TrendMiner application data will be migrated using remote storage services on AWS or Microsoft Azure.

Here's how you can accomplish this high level. More details will follow after TrendMiner Application 2024.R2 has been released.
Upgrade the Current Application:
Provision a New AlmaLinux or RHEL 9 Instance
Install the TrendMiner Application on the new AlmaLinux or RHEL 9 instance
Configure the remote backup in EdgeManager for the CentOS application
Backup the CentOS TrendMiner Application Data
Configure the remote backup in EdgeManager for the AlmaLinux or Redhat 9 Instance
Restore the TrendMiner Application Data on the new AlmaLinux or RHEL 9 Instance
Test the Setup
Switch to the New Setup
On-prem → Private Cloud with remote storage on AWS/Azure
Warning
This procedure is only supported as from TrendMiner Version 2024.R2
In this scenario, you are transitioning from an on-premises setup to a private cloud environment while using remote storage services on AWS or Microsoft Azure.

Upgrade the Current Applications
Provision a New AlmaLinux or Redhat 9 Instance in the Private Cloud
Install the TrendMiner Application on the AlmaLinux or Redhat 9 Instance
Configure the remote backup in ConfigHub for the CentOS application
Backup the CentOS TrendMiner Application Data
Configure the remote backup in EdgeManager for the AlmaLinux or Redhat 9 Instance
Restore the TrendMiner Application Data on the AlmaLinux or Redhat 9 Instance
Test the Setup
Switch to the New Setup
On-prem → On-prem with using TrendMiner Backup & Import
Warning
This procedure is only supported as from TrendMiner Version 2024.R2
In this scenario, you are transitioning from an on-premises CentOS setup to an on-premises AlmaLinux setup, and you are not using remote storage for backup and restore. Instead, you will use the TrendMiner Backup & Import feature in EdgeManager for data migration.
Important
The EdgeManager Local Backup & Import will NOT restore all data!
Only the application configuration and work items will be restored. Tag indexes will be lost and will need to be re-indexed.
