migration_prefixedit

This setting is used by the reindex action.

If the destination index is set to MIGRATION, Curator will reindex all selected indices one by one until they have all been reindexed. By configuring migration_prefix, a value can prepend each of those index names. For example, if I were reindexing index1, index2, and index3, and migration_prefix were set to new-, then the reindexed indices would be named new-index1, new-index2, and new-index3:

actions:
  1:
    description: >-
      Reindex index1, index2, and index3 with a prefix of new-, resulting in
      indices named new-index1, new-index2, and new-index3
    action: reindex
    options:
      wait_interval: 9
      max_wait: -1
      migration_prefix: new-
      request_body:
        source:
          index: ["index1", "index2", "index3"]
        dest:
          index: MIGRATION
    filters:
    - filtertype: none

migration_prefix can be used in conjunction with migration_suffix
