A year or so ago, I needed to migrate squeeze to another machine, and that was enough work for me in one go, without going through the trauma of a version upgrade at the same time. It was a 32 to 64 bit transition, so just moving the hard drive and praying was not an option. A version upgrade will always have the possibility of bringing a significant configuration change to some packages, and with a package that is already configured well away from default, you will have neither the option of using the new maintainer's file nor of keeping your own, nor even just pasting some diffs. I hit this one with exim4, on what I think was an etch to lenny upgrade. The later exim4 had dropped support for debconf, which my previous configuration had used in many places. Just for added fun, the failed configuration left exim4 uninstallable and unpurgeable, and even dpkg used in the height of anger with lots of -f didn't help. I had to resort to deleting files manually. With a same-OS migration, you at least stand a good chance of just being able to copy over the configuration files. Even that isn't a certainty, since you may be migrating an upgraded OS to a clean installation, and there may be significant differences. If you've upgraded from lenny to squeeze and then to wheezy, a clean wheezy base installation with the same additional packages will almost certainly not result in an identical system, not even the same set of packages. So I'd go with a two-stage approach. At worst, it isn't more than a small amount of extra work, since whatever difficulties are encountered in each stage would probably all have been problems in a one-stage attempt. It may well be less work, if a one-stage attempt results in a real show-stopper. He is at least in the position of having a working system, and not being under time pressure to fix things, as is the case with an in-place migration. This would tip the balance for me towards migrating first, then upgrading, while my original machine was still running undisturbed. -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
