Is it possible to rename an index along with moving data from the old index to new index name?

We are trying to standardize our nomenclature on indexes. Is it possible to rename an index along with moving data from the old index to new index name?

Example:
index "fit_azure" need to change to "top-azure"

Are there things to consider that I'm probably not keeping in mind. My concerns doing this are:
Would renaming the index require re-ingesting of data?
If so, what about when ingesting data into an index can sometimes delete the log on the on the system inputting into splunk?
How would this impact storage, hot/warm/cold and all that?
- would previous storage be inaccessible to the new index naming?
Would permissions on viewing the index change?

If you're using stand-alone (non-clustered) indexers, Here is the method to rename index (requires backend access and possible downtime).

It'll not be considered for license utilization (no re-ingestion). It will keep the same folder structure in new index so no change in warm/cold status. All hot buckets will be rolled to warm as Splunk would be restarted. All accesses to index are managed in authorize.conf so depending upon how your accesses are setup, there may be changes.
