Elastic dump from 8.9 to 2.3 throwing errors

Question

When I ran the below command

C:\Users\ASDF>elasticdump --input=http://username:pwd@domainname/indexnameone/ --output=http://username:pwd@domainnameone/indexnametwo   --type=data

The error is

BAD_REQUEST: {"error":{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: type is missing;2: type is missing;

Answer 1

The document types were removed in the 5.x-7.x timeframe. So you are trying to index from the version of elasticearch that doesn't support types into the version where types are mandatory. Try specifying type on your target index:

elasticdump --input=http://username:pwd@domainname/indexnameone/ --output=http://username:pwd@domainnameone/indexnametwo/typenametwo --type=data
