I'm looking for current documentation/process for adding additional indexers and moving to dedicated search head.
Our current setup is a search head + indexer and 2 dedicated indexers.
We would like to add 2 new servers. 1 would be used as a dedicated search head and the other will be a dedicated indexer. So, net result would be 1 dedicated search head and 3 indexers. Also, not sure if I should remove search head from existing server or leave for summary indexes.
