Summary:The invention discloses a data migration processing method and device, and relates to the technical field of big data processing. A specific embodiment of the method comprises the following steps: constructing a plurality of data migration intermediate tables based on structural difference information and inter-table difference information of a data emigration party and a data immigration party; exporting to-be-migrated data in a data emigration party as data files, and respectively importing the data files into the plurality of data migration intermediate tables; and logic processing is performed on the imported data files in each data migration intermediate table, and the processed data files are migrated into a data migration party from the plurality of data migration intermediate tables. According to the implementation mode, exporting, processing, checking and warehousing work of data between different databases is completed by setting the intermediate table and cooperating with extensible and parameteriz
