[Mediawiki-l] How to change site name

[Frank Fulchiero]

I wanted to change our site name from acorn, to wiki.
I know this is generic, but have reasons to do it...

The root is already "wiki"

http://nutmeg.conncoll.edu/wiki/

Running MediaWiki 1.5.4

How can this be done?
Is it enough to change $wgSitename in LocalSettings.php?
Do any changes need to be made to the MySQL database?
Will this mess anything up when I upgrade to 1.1x in a few months?

Thanking anyone for answers,
