What is the source? What is the target in your example? ---

Issue in production.. We're not able re index it to new index with new mapping ---

So? What is the difference between old and new mapping? Did you remove the BBBB index before launching the reindex operation? ---

We are adding date field on to the mapping and BBBB is new index First we created the mapping and then tried reindexing the AAAA to BBBB ---

> [@hello4usharath](#): > > David when we execute re indexing why do doc.deleted get increased? That's what I want to understand actually. So that's the reason I asked for a full script which helps to understand what you are exactly doing. All the steps, please. I suspect that you are doing updates of existing documents, not reindexing to a fresh and clean index. That's why I'm asking. ---

before this we create ticket\_v2 mapping and run below command POST \_reindex { "source": { "index": "ticket\_v1" }, "dest": { "index": "ticket\_v2" } } ---

So you don't delete `ticket_v2`? ---

Could you also post the exact command that you are using for the reindex? Feel free to black out the index name Which version of Elasticsearch are you running? There have been a few bugs in the past If you need a quick fix I would consider to expunge the deleted documents using the force merge API [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-forcemerge.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-forcemerge.html) POST /twitter/\_forcemerge?only\_expunge\_deletes=true ---

We are not deleting ticket\_v2. While re indexing to ticket\_v2 doc.count matches with ticket\_v1 but doc.deleted doesn't and count gets increased by 4 to 5 times. If you see first post wherein first line doc.deleted is 84 and in second line nearly 20 thousand. What could be the issue? ---

why to do force merge it? we want to re index the data to new index with new mapping. while performing the re indexing docs.count gets matched but only concern is docs.deleted number varies for long time . That is concern we are using 5.2.0 version of elastic search. POST \_reindex { "source": { "index": "ticket\_v1" }, "dest": { "index": "ticket\_v2" } } ---

So upgrade is the first thing to do. Then create an empty target index. Which means DELETE target. Then launch a single run of reindex from source to target and share the results here. ---
