Migration Guide

v1 to v2

  • The product was renamed from VirusScan for Amazon S3 to bucketAV - Antivirus for Amazon S3.
  • EC2 instances now run on spot capacity. Set the parameter CapacityStrategy to OnDemandOnly to launch on-demand instances as before (more expensive).
  • The parameter VolumeSize was removed. No action is needed.
  • The SNS message subject changed from s3-virusscan s3://${BUCKET_NAME} to bucketAV Scan Result for S3 Bucket ${BUCKET_NAME}. No topic subscriber should rely on the subject.
