I have a debian woody box I set up a couple of years ago. It started out as a web/DNS/DHCP server. I have since moved the web server to a debian sarge box that was set up to get newer postfix/mysql/spamassasin/squirrelmail packages. So the only things this box does right now is act as a primary DNS server and as a DHCP server for the network. I want to move it up to sarge to set it up as a hot backup webserver. I want to get the mysql packages the same and such so I can setup this machine to replicate the mysql database and with subversion keep an exact backup of the website in case of any trouble. I am wondering if anyone has done an in-place upgrade from woody to sarge and ran across any "gotch-ya's". The main thing I am worried about is the kernel and difference I am going to run into getting it from 2.4 to 2.6. Thanks for the experiences. Rick
