Red Hat Enterprise Linux 7 (RHEL 7) and the derived CentOS 7 are nearing their end of support. To ensure continued reliability and security for TrendMiner, we are transitioning TrendMiner to run on to the long-term supported Red Hat Enterprise Linux 9 (RHEL 9) and AlmaLinux OS 9 distributions. Infrastructure can already be prepared based on these new OS’s and the new system requirements. A new pre-packaged virtual appliance image based on AlmaLinux 9 has been made available for this purpose.
Migration options
There are 2 options to migrate the existing server data to the new instance:
- Full migration including index data based on remote backup & restore (Azure Blob Storage or AWS S3 Bucket are the supported options)
- Work migration excluding index data based on local backup & restore
The full migration is highly recommended as it will ensure the smoothest migration path with the least disturbances for end-users.
Full details, with additional considerations, can be found in our documentation center under the dedicated OS migration section.
What should you do today?
There are a number of important actions you should take to prepare for a smooth transition:
- Set up the new TrendMiner infrastructure according to the new OS and system resource requirements
- Ensure your existing TrendMiner instance is already upgraded to the latest version (2024.R1.x) in anticipation of the 2024.R2 release
- Prepare remote storage if you opt for the full migration (highly recommended)
- Ensure access to internal resources (e.g. IT colleagues) to manage firewalls, retrieve the required certificates etc. More details on the required actions are available in the FAQs (see below).
- Set up a communication plan for your internal TrendMiner community. Make sure you are able to inform end-users about upcoming downtime during the migration period.
If you intend to upgrade immediately when the 2024.R2.0 release is generally available, please inform our support team at support@trendminer.com. This way we can ensure proper planning for our engineers to be on standby.
