In another environment (SIT), We have taken a snapshot of 7.3.2 and upgraded the ES server to 7.16.2. Now, we would like to restore on that node.

ii) Is it necessary to delete indexes, data streams before restore ?
ii) please share the steps to restore entire ES node
Environment: Single Node Unix based VM.
