Writes to a source device are intercepted and it is determined whether data in the source device is being migrated to a target device. If data is being migrated, then the intercepted write is mirror written synchronously to both the source and the target. Data being migrated is read from a region of the source and written to a region of the target and also to a mirror writing memory location. The source region data is re-read and compared to the originally read data that is written to the mirror writing memory location. If the compared data does not match, the data migration from the source region to the target region (and to the mirror writing memory location) is repeated until the originally read data and the re-read data match."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Migration of data in a distributed environment","description":"Embodiments of the invention migrate dynamically changing data sets in a distributed application environment.
