保留LocalSettings.php file, AdminSettings.php file (if present),及"extensions"與"images"目錄
更新修改過的程式(待整理)

You will need an AdminSettings.php file set up in the correct format; see

AdminSettings.sample in the wiki root for more information and examples.

Major changes have been made to the schema from 1.4.x. The updater

has not been fully tested for all conditions, and might well break.

$wgDisableUploads has been replaced with $wgEnableUploads.

$wgWhitelistAccount has been replaced by the 'createaccount' permission key in $wgGroupPermissions. To emulate the old effect of setting:

 $wgWhitelistAccount['user'] = 0;

set:

 $wgGroupPermissions['*']['createaccount'] = false;

$wgWhitelistEdit has been replaced by the 'edit' permission key. To emulate the old effect of setting:

 $wgWhitelistEdit = true;

set:

 $wgGroupPermissions['*']['edit'] = false;

If $wgWhitelistRead is set, you must also disable the 'read' permission for it to take affect on anonymous users:

 $wgWhitelistRead = array( "Main Page", "Special:Userlogin" );
 $wgGroupPermissions['*']['read'] = false;

If using Memcached, you must enabled it differently now:

 $wgUseMemCached = true;

should be replaced with:

 $wgMainCacheType = CACHE_MEMCACHED;

Message changes:

A number of additional UI messages have been changed from HTML to wikitext, and will need to be manually fixed if customized.
