Searching logs in NLS with revoked license

[TX_Group_AG]

Hello everyone,

We installed the latest NLS 2024 server on a VM, due to end of support of RHEL7 which was a base OS up until version 2024R1.0.2.
After this version we were forced to go with new NLS installation which runs on CentOS 9.

Thing and question is:

after we revoke the license from the old NLS node and activate that license on the new server, will it still be possible for us to read the log history inside old NLS? at least for a number of days until new NLS fills in it's history buffer and we decide to decom the old nls?

Thank you,

Regards.

I would recommend following this guide to configure a snapshot of your existing NLS instance and then importing that snapshot's logstash indexes into your new cluster:

Yes, you should be able to access the log history on the old NLS server after revoking the license, provided bitlifethe old server remains operational for a short period. As long as you don't decommission the old server immediately, you can still retrieve the log data. Just ensure that you back up any necessary logs or data before transitioning fully to the new server. It's always a good idea to check the specific documentation for your NLS version to confirm any limitations or recommendations regarding log access during this process.

If the new NLS installation is running on CentOS 9, you will still be able to access the log history on the old NLS server after revoking the license. However, you will need to ensure that the old server remains up for a short period of time. As long as you do not immediately decommission the old server, you will still be able to retrieve the log data.
