As most migration scripts it's ugly and run only one and thrown to trash after an successful run. Please be careful and run it in an save environment / folder. I run it on the new IMGAPI server so localhost:8080 could be used for the connection.

# Migrate from datasets to IMGAPI. This script is build to migrate
# from the old datasets.at server to the new Joyent IMGAPI server.

# On other scripts you find the joyent-imgapi tool. I recommend using
# the imgapi-cli because it provides the feature of basic auth to the
# IMGAPI server.
IMGAPI_CLI='/opt/local/lib/node_modules/imgapi-cli/bin/imgapi-cli'

# Authentication user and password, separated by colon. If you use
# other authentication you could also set it to "none".
IMGAPI_CLI_AUTH='basic'
IMGAPI_AUTH='username:password'

# Source datasets server
DATASETS_SOURCE='http://datasets.dev.fruky.net'


# Download a list of all images on the server
UUIDS=$(curl -s ${DATASETS_SOURCE}/images | json -a uuid)

# Download image, extract and upload
for uuid in ${UUIDS}; do
	curl -Os ${DATASETS_SOURCE}/api/export/${uuid}
	tar xf ${uuid}

	# Which files exists
	files=$(tar tf ${uuid})
	# Workaround for the published_at date
	sed -i 's|"published_at": "\(.*\)\.\([0-9]\{3\}\).*Z",|"published_at": "\1.\2Z",|g' *.dsmanifest

	# Upload to IMGAPI
	${IMGAPI_CLI} import --user ${IMGAPI_AUTH} -m *-imgapi.dsmanifest -f *.zfs.gz

	# Cleanup
	rm ${files}
	rm ${uuid}
