Hello,

I have done an update from MW 1.3.x to 1.11 a few month ago. (It was a hard trip ...) This is how it work for me (step by step and all from command line):

* Update to 1.4.15 without problems, change LocalSettings.php according to help:

from $wgStylePath = "$wgScriptPath/stylesheets"; $wgStyleDirectory = "$IP/stylesheets"; $wgLogo = "$wgStylePath/images/wiki.png";

to this: $wgStylePath = "$wgScriptPath/skins"; $wgStyleDirectory = "$IP/skins"; $wgLogo = "$wgStylePath/common/images/wiki.png";

* No the tricky part: To update from 1.4.15 to 1.5.8 I did this:

** first run Upgrade1_5.php. Should convert database from latin to utf-8, but only links and special pages are converted, the content of articels are still latin. ** Dump the database with latin1, open it with an editor (e.g. TextWrangler), save it as UTF-8. Find and replace special characters (it was german - äöüÄÖÜß, dash, accents ... I missed a few, so we had to change them manually in the articel later ...) ** Import database as UTF-8 ** run update.php ** change LocalSettings.php: wgDisableUploads has been replaced with $wgEnableUploads

* Then it went on with no problems: ** Update to 1.6.10 ** Update to 1.11.1

Kind regards, Raul
