Future transit from testing to stable with sarge possible?

[Tobias Reckhard <jester71@gmx.net>]

Hi

I've got a couple of systems running on Debian sarge/testing and would 
prefer to have them on stable, but with the upcoming transition of sarge 
to stable, it's not worth the effort to reinstall the machines using 
woody, since I hope to be able to stick with sarge and thereby transit 
from testing to stable seemlessly. Am I being naive or is it sufficient 
to replace 'testing' with 'sarge' in /etc/apt/sources.list?

Cheers,
Tobias
