Amazon EC2 - Convert EBS root device with instance store root device

Question

I see that you can convert an instance stored instance to be EBS backed as this question shows. However, I want to do the opposite, take an EBS backed instance and convert

Answer 1

You can try this:

# Install ec2-tools (http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip)

$ export EC2_PRIVATE_KEY=/path/to/your/key.pem
$ export EC2_CERT=/path/to/your/sert.pem
$ export AWS_ACCOUNT_ID=XXXX-XXXX-XXXX
$ export AWS_KEY=YOURAWSKEY
$ export AWS_SECRET_KEY=YOURAWSSECRETKEY

$ ec2-bundle-vol -d /tmp -k $EC2_PRIVATE_KEY -c $EC2_CERT -u $AWS_ACCOUNT_ID
$ ec2-upload-bundle -b s3-bucket-name -m /tmp/image.manifest.xml -a $AWS_KEY -s $AWS_SECRET_KEY
$ ec2-register s3-bucket-name/image.manifest.xml -K $EC2_PRIVATE_KEY -C $EC2_CERT --region eu-west-1
# In command above you can choose another region (e.g us-west-1)
# By running command above you will see on your screen something like this: IMAGE   ami-3cc1a4a
# Now you can create new instance based on your just registered ami-3cc1a4a using ec2-tools or Amazon Console

Good luck!
