HI @amalk12
No, you don’t have to initialize the SG plugin again. TLS certificates are not stored in the SG configuration.
TLS certificates are used to secure connection between the nodes (transport layer 9300-9400) and access to the cluster (HTTP 9200). TLS certificates are configurable only at the elasticsearch.yml and kibana.yml level.
The SG initialization is done only once and any further changes can be made with sgadmin.sh in SG Classic and sgctl.sh in SG FLX.
