Es5 is not upgradable from 2.x

Elastic Stack Elasticsearch

Hi,

I ran elasticsearch-migration on es 2.4.0 and got warned about the number of fields i specific index.

does it mean that we cannot upgrade to es5 with current data?

Thanks in advanced.

You can change the index settings in 5.0 with index.mapping.total_fields.limit for new indices.
Old indices should work even if you went over the default limit.
