In order to upgrade 2.3.z elasticsearch to 5.x, I have successfully installed elasticsearch migration plugin, but when linking to http://localhost:9200/_plugin/elasticsearch-migration/ I get a blank page.
Can someone let me know the following:-
- Do I have to install the plugin all the machines in the cluster?
- Do I have to restart all the machines in the cluster?
I have already tried the steps as mentioned here. But still I am getting a blank page.
