When running migration it throws the following exception:

$ rails db:migrate
rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:

Directly inheriting from ActiveRecord::Migration is not supported. Please specify the Rails release the migration was written for:

class CreateWorkflowProcesses < ActiveRecord::Migration[4.2]

Is it not supported for these versions?

$ ruby --version
ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-linux]
$ rails --version
Rails 5.1.4
