We have xpack.security setup on ElasticSearch and need to move to Opensearch
Is there any easy way to migrate with minimal downtime or would it be a case of disabling xpack.security, and doing a rolling cluster upgrade with Opensearch without security and then starting from scratch with security in Opensearch?
We are also thinking of reducing the number of nodes in Elasticsearch to allow a new cluster to be created and then importing the data into this
