Re: Upgrade from 1.1 to 2.x
- Hi,The information in the release note are very limited and don't give any guidance. It doesn't even say it will occur by magic, which is more or less the case, I have to admit, as I upgrade without much hurdle.Some of the release notes mention upgrade from 1.X, some don't. By reading the release notes for every sigle release, I didn't found any word of warning, but no words telling it's fine to do it this way from any version to 'this' version.Additionnaly, there is no indications in the log file about the update of the version. might be due to the verbose setting, but I think it could be valuable to have some mention of what have been changed, and what might/should be done on the config files whatever verbosity setting for the log.Anyway, thanks for you words, I've taken the risk of the update, and it went fine so far.Alexandre2007/12/26, Wietse Venema <wietse@...>:

DO read the RELEASE_NOTES files. There is one for every release.

If you build from source, or if you use a competently packaged
version, that would suffice.
However, DO NOT copy your OLD main.cf etc. files over the NEW
files. Instead, let the install procedure upgrade the old files.
