[Mediawiki-l] Help upgrading...

[James Shepard]

Hi.

I am running a Mediawiki based wiki for professional airline pilots  
within British Airways aimed at distributing route information.

The version info is as follows:

MediaWiki (http://wikipedia.sf.net/): 1.3.11
PHP (http://www.php.net/): 4.3.10 (cgi)
MySQL (http://www.mysql.com/): 3.23.56

I wondered if somebody a bit more au fait with upgrading than me  
would help me upgrade the media wiki software to a more current  
version? I am wary of doing it myself in case I screw up the current  
database.

Any help would be greatly appreciated.

Thanks in advance
