So, to clarify, you're saying I don't need to run these SQL queries? (the sql files) Also, is it ok to upgrade directly from 4.0 to 4.1.1 using the instructions here: http://ez.no/developer/news/ez_publish_4_1_1_and_4_0_4_released ? Thanks.

I experienced similar problems when updating from 3.10.1 to 4.1.1
I'm a fan of eZ, but upgrading the database gets more and more user-unfriendly each time.
In terms of the Database, upgrading from 3.10.1 to 4.x should be easy, but i ran into these issues:
1. There is no real upgrade documenation available for upgrading to 4.1 (i mean, have a look at http://ez.no/doc/ez_publish/upgrading ....)
2. You have to either follow the changelogs of each minor version closely or use trial and error in order to decide which SQL files to run and what to do if they don't. Usually, you look into them, once they stop with an error like "duplicate key name" and there you find some SQL lines with comments like "--- from 3.10.1 ---" ... somewhere there used to be a hint, what these means: Should we use these lines, when i ugrade vom 3.10.1 ... i should we not use them? Whatever you do: When you run the script the 2nd time, i will usually stop in the first lines, as it has run halfway through and now it stumbled again.... This is not the ez way to do ANY update.
Josh (and all other)... what i do is: open the upgrade scripts from the corresponding directories in a text editor and copy and paste them block-wise (or line-by-line) into your SQL client (I use phpMyAdmin for that). That way, you can see, which parts work and which don't. Errors, that tell you, that a key or a column already exists can be ignored, as this means, that this key or columns are already there, usually created by a prior upgrade script statement. If you encounter an error, just go ahead with the next line(s) from the same SQL script.
Not running the SQL scripts at all is probably not a good idea. Among other things, the script store your current ez publish version in some DB table and i assume, that there ARE some (even minor) DB changes between 4.0 and 4.1.1.
@ez: We have loads of PHP scripts for updating, which usually run quite fine. Why can't we have some DB-update-script, which does, what i do manually here: connect to the DB, select the right SQL command file(s), run them line by line and respond more clever then the mysql CLI client to errors? This tool could also parse all the "directives" in the SQL files, which indicate whether the run a specific bunch of lines or not.
Or can't you automatically(!) create "diff" files for the DB structure from any supported older version to the current version, so we'd only have to run ONE SQL command in order to get from 3.10.1 to 4.1.1 for example. Sorry, but i feel really uneasy, when i think of the 10+ ez3 installations, that i need to update to ez4.x in the next time.

<quote>4.0.0 to 4.1.1</quote> Not really the best way to go at it. The only upgrade path supported by eZ is: a.a.a => a.a.latest => a.b.x This means you should first try to update to 4.0.4, and from there go to 4.1. Regarding the sql scripts, it is a bit counterintuitive, but if you have already passed by version x, you need to actually skip the part between the comments "from version x"
hope it helps

Well, you are still eZ Systems crew, so you probably know more than me about what the 'supported' upgrade paths are these days. If this is only from 4.0.4, is it somewhere documented? As each person who's upgrading should remove a bunch of SQL then from 4.0.0-to-4.1.0 himself. I'm talking here about 'supported' upgrade paths now, not about 'possible' upgrade paths, as you can go straight from 3.9 to 4.1 as well if you know what you are doing.

Err, no. 4.0.x to 4.1.y is still supported, I think someone is confused by the fact that the file is named dbupdate-4.0.0-to-4.1.0, but if you open it, you can always see what kind of query's to skip. IMO: Even though it involves a bit more manual work the best thing is to always upgrade 4.0.x to 4.1.y where both x and y is as high as possible. Why? bug fixes, especially to upgrade scripts.. But you still need to run dbupdate-4.0.0-to-4.1.0 (included in the 4.1.1 version) before you run dbupdate-4.1.0-to-4.1.1 and so on. An upgrade wizard that takes care of running db updates and checking requirements changes would really be nice to avoid this.. We will discuss and define 4.2 road map next week, and this is already proposed as one of the features we have to have in 4.2

As you ask us to look in the documentation I'd like to quote: "This section describes how to upgrade your existing eZ Publish 4.0.x installation to version 4.1.y. If you are upgrading from version 4.0.3 or earlier, you need to first upgrade to 4.0.3 before you can upgrade to 4.1. (Refer to either "Upgrading from 3.10.x to 4.0.y" or "Upgrading from 4.0.x to 4.0.y" depending on which version you are currently running.) " upgrade to 4.0.3, nothing written about 4.0.4 or maybe it is an error? And there is still nothing written about deleting script part which should'nt be there according to the line above. Is that the way you understand documentation? <b>I really like Ez-publish, but... upgrading sucks!"</b>

I didn't try the upgrade to 4.2 yet.
@ez: I guess, the Script for applying the SQL upgrade snippets didn't make it into the 4.2 release? Is there a bug/enhancement report for it, so we can track this?
Quoting the Upgrade docs in http://ez.no/doc/ez_publish/upgrading/upgrading_to_4_2/upgrading_from_4_1_x_to_4_2_y :
Step 4: Upgrading the database
The update script for the database is located in
<eZP root>/update/database/<mysql|postgresql>/4.2/dbupdate-4.1.0-to-4.2.0.sql
You can run this with the appropriate command line tool or application
Are you at ez aware, that there may be web admins, who must upgrade eZP, which may not be able to apply the .sql files, e.g. because they don't have access to the DB?
Any web admin can copy some files to his webserver and probably is able to run Upgrade scripts from the Shell (if he has SSH access), but maybe he is not the DB admin and will need to contact his fellow DB-guy and discuss the SQL scripts -line by line- with him?
Upgrading really is way to complicated, and one reason is the SQL upgrade scripts fun.
Please provide an PHP script, that runs the SQL commands. Can't be so difficult to read the connection paramters from the INI files and pass the SQL commands to the DB? I just think, it's too much to expect from us to identify the SQL script to READ them line-by-line and edit them, before we can execute them and hope, they run through without any errors or warnings.
