Rails Migration files update by regular expression

We recently upgrade from rails 4 to rails 5 and while running rspec migration need to update all migration file by adding [5.0]

From “ActiveRecord::Migration”

To “ActiveRecord::Migration[5.0]”

We have around 400 files and changing manually is hard. So small script with regular expression to replace “ActiveRecord::Migration” to “ActiveRecord::Migration[5.0]”

`To “ActiveRecord::Migration[5.0]”

Dir.glob("#{Rails.root}/db/migrate/*").each do |file_name|text =, "w") {|file| file << text.gsub(/\bActiveRecord::Migration\b/,"ActiveRecord::Migration[5.0]") }end
