I am having index in the following format
logstash-system.info and the index contains last 5 years of data. I want to purge only last 1 year of data in that index. Is it possible to delete it using any other tool.
I have come across many information in blogs that it can be resolved using curator but they suggesting the index format should be in the followign format logstash-system.info-[YYYY.MM.dd] to achieve. I c an't do this because I am using latest version of kibana in that I am getting deprecated warning when I suppose to create index with time format.
Any guidnace will be helpful for me to proceed further.
