Earlier this year I migrated (aptitude upgrade) my home desktop from Sarge to Ubuntu 5.10 (if I remember correctly), then to 6.06 (and from there to 8.04, the next LTS, and on to 8.10 and 9.04).
This was not without some pain. 6.06 was one of the stages where things worked pretty well, however. Most of my issues were X-server and desktop related. I gather your client's system is a server, so this may not be an issue. On the other hand, being a desktop system, I don't have apache, PHP or any of those type of things on it. So I have no experience how this style of migration/upgrade would work for that type of configuration.
Needless to say, you should test carefully before attempting anything like this on a production system.
If "server upgrade" also means new hardware, than a fresh install of "dapper", and then migrate the app, would be the way to go.

Hi all, this is probably crying for flames but I need to ask anyway: I have a customer who is running a very large project on PHP4. Because of subtle object usage details in programming, a port to PHP5 would be pretty identical to a complete rewrite (about 6-8 man-months estimated) and is not financially feasible because of short budgets (like everywhere). However, a server upgrade is on the list (they still run sarge) and I need to know if anyone knows about a repository or something where anyone hosts some sort of more-or-less-maintained backport repository for ANY debian or deb-based Linux-Distribution that still gets security updates! (they are on sarge, currently) Please dont tell me that they wont get around a PHP upgrade sooner or later because I know and I told them and they dont want it now. All I want to do is make the best out of the situation and to achieve that I need to move away from sarge, to get at least an OS with security updates which would be an improvement already. If you have any hint, I'd strongly appreciate a reply. Thank you!
