huh? without loosing download queue?? what you mean?
every time you shut it down...you loose your queue postion...
so basically remove the old rpm(you can do this while amule is running)
install the new one and then whenever you shutdown your amule or computer for example next time you start you will have the new version installed.
but ther is NO way of installing the new version without shutting the old one down
