Setting up ESA Communication

Set ESA communication in cases, such as, change of the ESA IP address, change of the ESA certificates, adding the ESA IP address for cloud platforms, and joining the DSG in an existing cluster.

Note: Ensure that SSL synchronization is performed only once. If you are performing the ESA communication step multiple times, it is recommended to skip SSL synchronization.
