Is there a way to alter a table?

[Sasha]

I would like to change encoding for one of my tables by using Percona, but the only way I googled is to execute a custom SQL like:

class ChangeCommentsToUtf8mb4 < ActiveRecord::Migration
  def up
    execute "ALTER TABLE comments CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_bin"
  end
end

but in this case, it won't run with Percona.
Is there a way to alter a table and still run it via Percona?

I see that execute works via Percona as well, somehow I missed it. Sorry
