i have a question about migrate cluster, my customer want to upgrade os from centOS to oracle linux, it is possible migrate cluster with different OS?
Solved! Go to Solution.
Hi @sandi_pusghiyan ,
At our customers we always extend the existing cluster with a new leg or legs with the target operating system.
After the data replication old leg or legs are removed from the cluster.
I hope it helps.
Yes. Exactly same way as you install any OS patch. https://www.dynatrace.com/support/help/managed-cluster/operation/apply-operating-system-patches-to-a...
You can also use backup and restore method if you want to do it quickly, I tried it like 3 times and it worked fine.
Keep in mind that in case of backup restore you lose the user session data (maybe it is important for some clients).
yes i now that problem, we can lose the user session data and all distributed traces right?
oke, my plan is the same with you, but its first time for me, so im not confidence right now, can you explain in generallly step by step with backup and restore method?
To configure automatic backup for a Dynatrace Managed cluster
In the Dynatrace menu, go to Settings > Backup.
Enable cluster backup and choose the scope:
User sessions may contain sensitive information.
Exclude user sessions from the backup to remain compliant with GDPR.
Exclude timeseries metric data from the backup if your historical data isn't relevant and you only want to retain configuration data.
Include backup of Log Monitoring events.
(Optional) Select data center. This step is required only if you have multiple data center deployment (Premium High Availability deployment). For more information on Premium High Availability deployments, see High availability for multi-data centers and Disaster recovery from backup
Provide a full path to the mounted network file storage where backup archives are stored.
Configure start time.
For cluster restore, please follow the below document and put into consideration
For further details, please check the main document for cluster backup and restore.
