Hello, I was upgrading elasticsearch 5.X version to 7.3. I read ES removed mapping type. Right now, I have a mapping type in my structure. Under one index, I have around 10 different mapping type and each mapping type has different mapping. Ex : IndexName -- MappingType -- Mapping ABC -- Car -- { "created\_on": {"type":"date"}} ABC -- MoterCyle -- { "created\_on": {"type":"date"}} That is just an example Now if I want to upgrade to 7.3(current) How many changes I need to do? I read the articles of elasticsearch removing of mapping type. but could not get much. Can someone help me? ---

The generic advice would be to create one separate index per type. So, create one index for `Car` and another one for `MoterCyle`. ---

Thanks abdon. Will Index name per type will cause any issue in future? Right now, For one customer, I have one index and under that index there are 10 mapping type. So If I create 10 different index for one customer, will it be going to impact any performance issue? I have more than 200 customers. the number of indexes will be 10X from right now when I will go to 7.X. In that case I might need to add additional nodes also. Also, I need to use multi index for search in that case right? Was there any alternative? ---

Having a lot of small indices and shards will be very inefficient and likely cause problems. If I recall correctly Elasticsearch 5.x prevents you from having different mappings for different types within an index, so the easiest solution is probably to add a field to each document which contains the type of the document. You can filter on this when you query to limit searches to specific type(s). ---

Thanks, @Christian_Dahlqvist. Probably I will add index type in each document's field and while searching the document, I will add the filter to get the document. It will help me for upgrading the ES version. ---
