If you know what you're doing, the upgrade process is the same for any Debian-based distribution, and I've never had it fail in an unresolvable way. I assume the same is true for Elementary, though I've never used it. Distros like Ubuntu make upgrade failures harder to work through because they go to some lengths to wrap the dist upgrade process in some software that reverts everything if anything goes wrong. But if you just move all your apt sources forward to the next distro and read any specific error messages you get, you can generally work through them. Distros other than Debian itself don't typically recommend that you do things this way, and instead have some extra software for going through the process. But the Debian way still works on them.
