The full upgrade will always remove modifications...

And upgrading between major versions would never preserve modifications -- because the coding it too different.
As a matter of fact, you will have to uninstall your 1.1.x themes as well, since none of the 1.1.x themes will work on the 2.0.x versions

Your DATA, however, will be preserved and the database updated.  Posts, members, pms, settings, these are all preserved, because the database is upgraded, not replaced.

Thats too bad, but ok, we have to deal with it and make it the best.

Is it possible i do the upgrade and try it on another map in the root to whats happend exactly? For example now it is.../forum and i want to try in .../forum2

Or, if i do the upgrade, will the old forum stop working because of the databse upgrade?

the database changes make the upgrade incompatible with the old version files...   they are looking for the wrong table names, etc...

You could create a test copy (completely copy your database and then copy the files into a different directory, then point the test files to the test database using repair_settings.php)
However, I have generally found this to be unnecessary...   as long as you take a good backup before attempting the upgrade - you can always restore the backup

Yes.
The "large upgrade" features a clean set of files which will always kill any custom coding you have in place. Furthermore, 1.1.x coding is generally not compatible with 2.0.x

That being said... If you used, eg, Ads Management MOD for your sponsors banners, then you would reinstall the MOD in 2.0 and the banners would still be there. But if you coded everything by hand, then you clearly need to redo it again after upgrade...

Margarett, yes it was coded bij hand, with help off this forum, this was the topic.
If i upgrade to 2.0.10 i want the same, i think i will ask in that topic 

Is there any existing MOD for sponsor banners?

[margarett]

Ad Management is probably the most complete MOD for that.

That's a very interesting mod but i looks very difficult, as i see it now i have to write the html myself? That's quite a problem..
I will do some reading...thanks...
