We purchased the Splunk light license but previously we are running with Splunk enterprise trial, it got expired and nothing was showing on the dashboard.
Now can we apply Splunk light license on Splunk enterprise so that our settings which were there earlier will be continued and no need to configure Splunk light?
No, you can't apply Splunk Light License to Splunk Enterprise License
as per Splunk docs:
Purchase and install a Splunk Enterprise license to upgrade to Splunk Enterprise.
When you upgrade to Splunk Enterprise, your data, searches, alerts, knowledge objects, and settings migrate seamlessly. **If you have add-ons enabled, they remain active and appear in the Apps browser view of Splunk Enterprise.
