Abstract
Systems, methods, and computer storage media for upgrading a domain in a distributed computing environment are provided. Upgrading of the domain includes preparing for the upgrade, upgrading, and finalizing the upgrade. The preparation of the domain includes ensuring predefined quantities of role instances are available in domains other than the upgrade domain. The preparation also includes ensuring that a predefined number of extent replicas are available in domains other than the upgrade domain. The preparation may also include checkpointing partitions within the upgrade domain to facilitate faster loading once transferred to a domain other than the upgrade domain. The finalization may include allowing nodes within the upgrade domain to resume functionality that was suspended during the upgrade.
