Upgrading to ArcGIS 10.1 on Amazon EC2

[StephenLead]

I'm currently running ArcGIS Server 10.0 on the Amazon EC2 and I'd like to upgrade to 10.1

What is the correct/easiest upgrade process?

The Resource Center lists http://resources.arcgis.com/content/arcgisserver/10.0/arcgis-server-amazon which refers to 10.0 only.

Thanks,
Steve
