I think you could use "postconf -n" on your new system with your old main.cf. It will show you differences between Default and your configuration. You can compare this output line by line with your main.cf to remove default lines. To get an overview of all options, you could use "postconf " to see all options and compare, if the remaining options from your old main.cf are still existing in the newer version. A last step might be to go through "man 5 postconf" and quickly zap over the parameter names taken from your main.cf to see what is deprecated. I am not sure, if this is an elegant way to "upgrade", but I would do it this way :-) Concerning your db-files. If they were created from hash, btree whatever files, I think you should not copy them, simply recreate it by running postmap (see the man page). But I do not give any guarantees ;-) Christian --- Roessner-Network-Solutions Bachelor of Science Informatik Nahrungsberg 81, 35390 Gießen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com
