Data Model extend Summary Range: Should I rebuild or update do nothing?

Hello, everybody!

I have accelerated Data Model «DA Host OS» set with 7 Days Summary Range and it works as expected:

What if now I need to extend this Summary Range to 1 Month and later to 3 Months - after I change the setting and click «Save» should I do anything else? I am especially interested if I should completely rebuild the summaries or Splunk will reuse already calculated 7 days summaries and start calculate and store newly summaries to 1-3 Months depth? I have Backfill Range set to Match Summary Range.

I checked the docs https://docs.splunk.com/Documentation/SplunkCloud/7.2.6/Knowledge/Managedatamodels «Rebuild a summary for an accelerated data model» and «Update summary metrics for an accelerated data model» but it is still not quite clear what should I do in my case.

Thanks for the advice!

Yes, you need to account for the significant increase in disk usage that extending the range incurs or you may cause data loss by freezing buckets early. It will keep what it has already and work farther backwards.
