My Cloudera Manager trial has expired. Would it be possible to change it to Cloudera Manager Express?
Thanks a lot,
I think this reply by @Alex may apply to your situation. He mentions higher up in the thread the need to remove the enterprise license key for contract customers if they chose not to renew. Perhaps he can clarify if it applies the same way in trial versions.

Thank you for looping me in, @cjervis.
I can confirm that if a trial license key has expired, there's 2 possible paths forward.
If by "trial" you're speaking of a formal enterprise support trial issued by Cloudera, the key does indeed need to be removed as noted earlier in this the thread linked by Cy.
If by "trial" you're referring to the 60-day key that is capable of being downloaded directly from cloudera.com, there is no action needed. Upon the 60 days expiring, the cluster will revert back to express.
If I can be of any further assistance please let me know. Thank you kindly.

Here's a page that describes the differences between the "Cloudera Enterprise" and "Cloudera Express" versions:
To specifically answer your question, the expiration of a trial license key will indeed remove features such as LDAP authentication to Cloudera Manager, as noted in the table on the above-referenced document. So, if your CM had been set up and configured to authenticate against an LDAP store it's possible that, yes, this will no longer be working correctly.
But, generally speaking, the expiration of a trial license key will not render a cluster un-usable, it's just simply that the enterprise functionality is no longer going to be available.

We are planning to downgrade the license version of Cloudera Enterprise to Express version.
Could you please recommend on what additional steps we would need to take care while doing the downgrade.
We are anyway planning to do ensure that we are not using the applications not available but in case you have experienced anything specific please let us know

Once the Enterprise License Key is removed, all of the enterprise functionality that is enabled by the Key is no longer going to be available. The functionality is documented here.
For example, the Enterprise version of the software enables the following (as well as other very important services such as Encryption and Key Management) =>
Advanced Features: Operational Reporting; Multi-Tenant Quota Management; Configuration History & Rollbacks; Rolling Updates & Service Restarts; SNMP Support; Support Integration (including scheduled diagnostics & proactive maintenance); Fine-Grained User Roles; & Automated Backup & Disaster Recovery
In terms of preparing your cluster for the removal of the Enterprise License Key, it's going to depend on what/which advanced features, or, other functionality you're using that is only available by virtue of using the Key.
Without knowing the specifics of how the cluster is configured or running, it's not possible to confirm the steps that should be performed in order to ensure you won't have an impact once the Key is removed.
If your cluster is dependent on any of the advanced features or other Enterprise functionality noted in the sheet I linked above, I would recommend proceeding with extreme caution before removing the License Key. If that is the case, I would recommend speaking to your Sales Representative at Cloudera to discuss options for being able to continue using the Enterprise version of the software.
Hope this helps.
