Migration of wiki - Wikitech-l

25 Mar 2005


      Hello
Sorry for my bad English, I'm French.
I need to migrate a mediwiki from a server to another. What is the best 
way to do it ?
I have done a migration of the database (dump + import), the I put the 
mediawiki archive on the new webserver, and I run the installation script:
the result:
----------------------------------------------------------------------
MediaWiki 1.4.0 installation

(index.php/Page_Title)

fail! Attempting to raise limit to 20M... ok.
