Hi, when i am start reindex from old index/type to new index/type there are a few complications: the docs takes fields and their contents that do not exist in the new index / type / mapping [but in the old index...] Field Types and their contents are not adapted to the new mapping; it is the given [by the old index] field mapping used I try to disable the dynamic field mapping [with "dynamic": "strict"], but when repeated the reindex no doc add to the new index. ES = 1.4.4 Reindex Tool = elasticsearch-reindex Is there a way to add only the fields and their contents that also exists in the new index and also adapted the field types and their contents to the new mapping? ---

> [@Dom\_Sie](#): > > ES = 1.4.4 You are unlikely to get help for such an old version. Sadly, a year is a long, long time in a project like Elasticsearch. But maybe you'll get lucky! > [@Dom\_Sie](#): > > "dynamic": "strict" Maybe you want `"dynamic": false` instead? That'll index the documents but the fields you've declared in the mapping won't be made available for search. They'll just be in the `_source`. It is my favorite value for `dynamic`. ---
