Microsoft states that Marketplace images for Windows Server 2016, published under the MicrosoftWindowsServer offer with the name WindowsServer, are then no longer available. Affected are Batch pools based on Windows Server 2016 Marketplace images; the relevant image SKUs include 2016-datacenter, 2016-datacenter-gensecond, 2016-datacenter-gs, 2016-datacenter-smalldisk, 2016-datacenter-smalldisk-g2, 2016-datacenter-with-containers and 2016-datacenter-with-containers-gs. Microsoft describes the required migration as a way to avoid service disruptions.",
  "migration_path": "1. Migrate Batch pools that use the affected Marketplace images to a supported Windows Server image by 12 Jan 2027. Microsoft recommends the latest version of Windows Server, if possible.\n2. Follow the Microsoft article on how to [update pool properties](https://learn.microsoft.com/azure/batch/batch-pool-update-properties) for migration guidance.\n3. Test the migration before updating production configurations.\n4. If the workload requires Windows Server 2016 after 12 Jan 2027, it may be possible to migrate to a Windows Server 2016 custom image with appropriate licensing and Azure ESU. See this [article](https://learn.microsoft.com/azure/batch/batch-sig-images). Azure Batch support for Windows Server 2016 still ends on 12 Jan 2027.",
