Carrierwave replace file after manipulate

I am running a background task, need to convert image to jpeg and store it. I am using CarrierWave uploader. Here's the code

  task reformat_user: :environment do
    User.all.each do |u|
        u.avatar.manipulate! do |av|
        av.format('jpg')
        av
      end
    end

However I could find no option to replace user avatar with a new one

If you need to replace user avatar with new, you just need to assign a new file to avatar

u.avatar = params[:file] # params[:file] contains the file uploaded by user from UI.
u.save!

OR this way

File.open('path_of_new_avatar') do |f|
  u.avatar = f
end
u.save!

I hope I understood your question correctly.
