After making a change in the current Report Definition rule,how can it fetch the old records as well in prod environment.

This was asked in an interview that if we are already having one Report definition in prod but now in Dev we add a declare index join in it and then redploy, will it still fetch the old records?before the change?

@TanyaS58 please check the below link for the answer. You need to run recreateindex— activity to populate old data.
