Comment 19 for bug 634487

Im a new EC2 user and have just come across this.

How do I start a t.micro instance as m1.small and retain the root volume Im using in the t.micro instance ?

I have installed other apps and have configuration and now find I need to change from openjdk to sun-java6-jdk. I dont want to have to go thru it all again, but when I use ec2-run-instances I get a new volume, so cant install the jdk where I want it !
