Hi Mustafa.
Upgrading an instance from stretch to buster should be essentially the
same as any other stretch->buster upgrade.
If desired, you can also create your own AMIs from scratch using the
same FAI configs that the cloud team uses to generate the official
images. In that case, the resulting image will be essentially
indistinguishable from the official ones, except they'll be owned by
your account. The steps to do this are:
install fai-server, fai-config, and fai-setup-storage (>= 5.7) and
qemu-utils.
Clone the FAI configs from https://salsa.debian.org/cloud-team/debian-cloud-images.git
Generate an image using:
/usr/sbin/fai-diskimage --verbose --hostname debian \
--class DEBIAN,CLOUD,BUSTER,BACKPORTS,EC2,IPV6_DHCP,AMD64,GRUB_CLOUD_AMD64,LINUX_IMAGE_BASE,LAST \
--size 8G --cspace /path/to/debian_cloud_images/build/fai_config \
/tmp/image.raw
Then write the resulting /tmp/image.raw file to a dedicated 8 GB EBS
volume with:
# dd if=/tmp/image.raw of=/dev/FOO bs=512k
Then register the EBS volume as an AMI using the 'aws ec2
register-image' command from the awscli package. Be sure to enable
EnaSupport and SriovNetSupport. You may find the wrapper script at
https://salsa.debian.org/noahm/ec2-image-builder/blob/master/bin/volume-to-ami.sh
convenient. This script is used in the publication of the stretch AMIs,
but not the buster AMIs. The process is essentially the same, though.
noah
