just slap this in your rake file or in lib/tasks 

namespace 'views' do
  desc 'Renames all your rhtml views to erb'
  task 'rename' do
    Dir.glob('app/views/**/*.rhtml').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.rhtml$/, '.erb')}`
    end
  end
end

or if you have rhtml and rxml you could probably use the following (untested) 

namespace 'views' do
  desc 'Renames all your rhtml views to erb'
  task 'rename' do
    Dir.glob('app/views/**/*.rhtml').each do |file|
      puts `svn mv #{file} #{file.gsub(/\.(rhtml|rxml)$/, '.erb')}`
    end
  end
end
