Hi Shubbham, Emir gave you accurate advice - you cannot (safely) change field types without reindexing. You may avoid errors for a time, and searches may even return the results you expect. But the type-change is still a ticking time bomb...Solr might try to merge segments down the road or do some other operation and blow up in unexpected ways. For more information on why this is, see the documentation here: https://lucene.apache.org/solr/guide/8_2/reindexing.html.
Unfortunately there's no way around it. This, by the way, is why the community strongly recommends against using schema-guessing mode for anything other than experimentation.
