Consistency is maintained across a first site and a second site upon a failure during independent migrations of a plurality of virtual machines in a consistency group from the first site to the second site wherein at least a first virtual machine is executing at the first site and wherein at least a second virtual machine is executing at the second site, by performing a consistent snapshot at the first site of one or more storage volumes employed by the virtual machines in the consistency group; and performing a consistent snapshot at the second site of one or more storage volumes employed by the virtual machines in the consistency group. When data for the virtual machines in the consistency group is stored on at least two storage volumes at a single site, an improved site-distributed consistency feature performs a consistent snapshot of the storage volumes in the consistency group on a plurality of replication engines at both the first and second sites."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining stored data consistency of a plurality of related virtual machines across a plurality of sites during migration","description":"Stored data consistency is maintained at source and destination sites upon a failure when migrating a plurality of related virtual machines from the source site to the destination site.
