Hi, We are on Solr 5.5.2 and wondering what is the best mechanism for replicating Solr indexes from a Disaster Recovery perspective. As I understand only from Solr6 onwards, we have CDCR. However, I couldn't find much content around index replication management for older versions. Wondering if there is any such documented solution is available.
>From replication perspective, apart from SolrColud collection data, what other information need to be copied over from source cluster to the target cluster? Should we copy the ZK data as well for the collection? TIA
