file: 004_rename_agile_ranks.rb

class RenameAgileRanks < Rails.version < '5.1' ? ActiveRecord::Migration : ActiveRecord::Migration[4.2]
  def up
    remove_index :agile_ranks, :issue_id if index_exists? :agile_ranks, :issue_id
    remove_index :agile_ranks, :position if index_exists? :agile_ranks, :position

    rename_table :agile_ranks, :agile_data

    add_index :agile_data, :issue_id
    add_index :agile_data, :position
  end

Can someone help how to solve ?
