Hello!

Is it possible to reindex an index with 3000 fields (index.mapping.total\_fields.limit is already set to 3000) to an index with default index.mapping.total\_fields.limit of 1000?

If yes, what are all the possible consiquences? IIIUC, I can ignore all the documents (using reindex API) that cannot be reindexed due to a new index already hit 1000 fields already, right?

Of course, given the context, I should find why do I have so many fields and really make it "stay" up to 1000, but right now I need to reindex it ASAP.

Thanks!  
Matt
