Hi,  
We plan the Upgrade from ES 2.4 to 5.6. After running the Elasticsearch Migration Helper v2.0.4 it comes out that some of our indices have more then 1000 field mapping (between 1010 and 1090). Will this be a problem for the upgrade itself and are those indices migrated too?

Thanks in advance for you help  
Regards  
-Rainer
