Attempt to migrate data to old indexes. I need to do this because data types changed, but I don't want to lose the old data.

01-migrate-bro-data.sh

# Move index names from bro-YYYY.MM.DD to bro-v1-YYYY.MM.DD
for item in $(curl -s -n  -XGET localhost:9200/_cat/indices | awk '/bro-/ { split($3,a,"-"); print a[2] }'); do
cat <<EOF | curl -s -n -XPOST localhost:9200/_reindex -d @- >/dev/null
{ "source": {"index": "bro-${item}"}, "dest": {"index": "bro.v1-${item}"} }
EOF
echo -e "\nCloned data from bro-${item} to bro.v1-${item}"
done

02-delete-old-indices.sh

for item in $(curl -s -n  -XGET localhost:9200/_cat/indices | awk '/bro-/ { print $3 }'); do 
  curl -s -n -XDELETE "localhost:9200/${item}"; 
  echo -e "\n Delete ${item}"; 
  echo -e "\nDeleted data from ${item}"
done
