Quick and dirty way of transferring enqueued sidekiq jobs from a non-namespaced sidekiq environment to a namespaced one

gistfile1.rb

no_namespace_redis = Sidekiq::RedisConnection.create({ url: ENV['REDISCLOUD_URL'] })
namespace_redis = Sidekiq::RedisConnection.create({ url: ENV['REDISCLOUD_URL'], namespace: "#{ENV['SIDEKIQ_NAMESPACE'] || Rails.env}" })


Sidekiq.instance_variable_set "@redis", no_namespace_redis

Sidekiq::Stats.new.queues
queue_names = Sidekiq::Stats.new.queues.select {|k,v| v.to_i > 0 }.keys

puts "Queue Names: #{queue_names.inspect}"
queue_names.each do |queue_name|
  Sidekiq::Queue.new(queue_name).each do |job|
    puts "queue: #{job.queue}"
    puts "klass: #{job.klass}"
    puts "args: #{job.args}"

    Sidekiq.instance_variable_set "@redis", namespace_redis
    Sidekiq::Client.push 'queue' => job.queue.to_s, 'class' => job.klass.constantize, 'args' => job.args
  end
  Sidekiq.instance_variable_set "@redis", no_namespace_redis
end
