→Skype - Business Version (MSI installer): minor version upgrades are OK with 6.0 without first uninstalling
The Skype IT Administrator's Guide, available from http://www.skype.com/go/administrators.guide (but for Skype 4.2), includes a table of registry keys for controlling policies such as automatic updates and becoming a supernode.
When using the MSI installer, you will may get an MSI error 1638 when doing a minor version upgrade (say from 5.0.152 to 5.0.156) (though this doesn't happen upgrading from for example 6.0.0.120 to 6.0.0.126), however since the product code doesn't change between minor versions, you can get around this by uninstalling based on the product code first, before running the normal installer like this:
<source lang="xml">
<!-- 5.0 product code -->
