Thread:Project:Support desk/Upgrade 1.4.12- current

Hello,

I have ancient mediawiki version (   MediaWiki (http://wikipedia.sf.net/): 1.4.12     PHP (http://www.php.net/): 5.2.6RC4-pl0-gentoo (apache2handler)     MySQL (http://www.mysql.com/): 4.1.22-log )

running on a gentoo box.

Is there a safe way how to upgrade to current version? I also think the database is still non-utf.

Anyone done something similar recently?

Thank you

Lubos Kolouch
