Hi there!

I've got some old indices with old mappings, because I just recently changed them. My indices are being created automatically every day because of data from logstash-forwarder and here's the question: if I deleted these old indices, would elasticsearch create them again automatically or are they just gone along with the logs?

Thanks in advance!
