AWS License Manager announces a new feature to upgrade EC2 instances with Ubuntu LTS (Long Term Support) operating system to Ubuntu Pro. With Ubuntu Pro subscription, customers get five years of Expanded Security Maintenance (ESM) on the Ubuntu LTS releases from Canonical. Using this License Manager feature, customers can upgrade their Ubuntu LTS instances in-place to Ubuntu Pro without needing to migrate to a new Ubuntu Pro Amazon Machine Image (AMI). For the use of upgraded EC2 instances with Ubuntu Pro, you will be charged on a per-second basis at the applicable On-Demand or Savings Plan rates for Ubuntu Pro.
