Updating from Squeeze to Wheezy

Hi, List :-) I have been holding fire in changing my desktop from my nice stable TDE on Squeeze until TDE for Wheezy sounded less dicey. I then delayed further when it recently stabilised because I had too much else going on in my life, and as I said, my system is great. I love TDE 3.5.13.2. But the time has come to upgrade. Other things have simmered down a bit, anyhow temporarily, so the time has come. In the past, I have always reinstalled. This time I want to try upgrading. When I edit my sources.list, I assume that I change the word squeeze to wheezy in my TDE repositories too? (Including Slávek's.) And that I just do a standard Debian update, dist-upgrade? (Yes, I have read the release notes. And yes, I shall make sure that I have got at least two backups of my data in at least two different places.) All advice and tips welcome. "Just go ahead"s perhaps even more welcome! Thanks, Lisi
