MW 1.22 and SMW 1.9beta install/upgrade
From semantic-mediawiki.org
Fragment of a discussion from Help talk:Installation
Hello. Yes, we are using Windows Server 2008 to run our Wiki's. The coming weeks I want to update MW & SMW and all other extensions. I am almost finished checking what needs to be done so that it works in one go and "nothing" goes wrong :). It is true that there are a lot of ways how to tackle an update but either Windows or Linux when you are using composer it works the same on both, well almost.
