(or just single nodes) will be started at the same time, and data will be migrated from the ES 5 to the ES 7 cluster. Note that it is possible to use a single node for both the source and the target port numbers on either the source or target cluster node. Changing ports requires a restart of the ES cluster you are modifying. In this example we will illustrate how to migrate by modifying the source because the first address that the tool will ask for is the target (ElasticSearch 7) cluster, not the ES 5 one. Note that it is also possible to change the index prefix to be different from the default context
