Comments on Upgrading from Debian 6 Squeeze with ISPConfig and courier/postfix to Debian 7 Wheezy

Excuse me but both Debian Squeeze and Debian Wheezy are both obsolete versions!  Why not directly from Debian Squeeze to Debian Jessie, the current stable version???  Please see the Debian release list.

This tutorial is about upgrading Debian and there are still many Debian 6 installs out there and even if you would want to update from Debian 6 to 8, yu will always update to Debian 7 fisrt and then to 8. The above tutorial are the notes that an ISPConfig user has taken while updating his live server from Debian 6 to 7.

"...and even if you would want to update from Debian 6 to 8, yu will always update to Debian 7 fisrt and then to 8."

That may be an approach for some, but not myself and many, if not most others.  Why do you say that you "MUST" upgrade from 6 to 7, then to 8???  Is there some technical reason that prevents 6 to 8 directly?

How To Upgrade Debian Squeeze To Wheezy   "The new Debian Wheezy has just been released."

This is an old outdated article.

Upgrading Debian 6 (“squeeze”) to Debian 7 (“wheezy”) with ISPConfig installed

Once again, this one was published on April 12, 2014, over two years ago.

You wrote your article on Aug 16, 2016, using outdated information.

First of all, why do you say I wrote an article? This is not a tutorial that I have written, see author link. I just outlined why it is still useful to have it. Second: The article is not outdated, it is about an older but still used Debian version, not the recent one, and there was no other complete guide available on that topic. Updating older systems makes it necessary to write about older software. Or do you think that it helps a user with Debian 6 to publish an article that covers Debian 7 to 8 only? There are still plenty of Debian 6 systems out there, so writing an updated article with new information and troubleshooting tips from a migration that has been done a few days ago is always helpful and none of the two referenced older guides contained all steps and troubleshooting tips. Third: where did I say that you must do something? I said that you would want to update from 6 to 7 to 8 and not directly, I'm doing quite a few updates on Debian systems and the likeliness to crash a system by skipping a major version in a dist-upgrade is much more likely then updating step by step. You miss a guide to update Debian 7 to 8 with ISPConfig? Feel free to write one, the user who wrote this guide last week had updated his system from 6 to 7, that's why these versions are covered in his tutorial. Maybe he writes another guide to update it to Debian 8, who knows. If he writes that guide and wants to publish it here, then you will find it at howtoforge.

I am the author of this How-To.I know debian 7 is outdated, yet I had a debian 6 server to upgrade, and as Till says, I would rather follow an upgrade path from one version to another, checking that everything runs smoothly on 7 rather than directly jump to 8 or 8.4, I think there is more risk involved in doing that.Also, upgrading one version at a time, I am more likely to be in the same position as thousands of other people on the internet who ran into the same kind of problems when upgrading, rather than "uuhhh... upgraded from 6 to 8.4 and I got this list of 3196 errors to fix, unsure where to start..."

I'm not trying to show off publishing stuff - I didn't include my twitter account of facebook or anything. And honestly I'm not very skilled at debian stuff. I just had this need to upgrade and ran into problems following existing tutorials, so I wrote my own notes. It's for me to re-use on a couple more upgrades I have to perform, but since I often rely on tutorials written by others, I wanted to give back something into the internet and help others in the same situation as me.

And finally... if you have no Debian 6 servers anymore, why bother reading this at all? You are clearly not in the target audience, Scotsgeek.
