SSAS Synchronization: Across different versions

Problem Statement: Synchronization between different builds or versions of Analysis Services.

Solution: The Synchronize Database Wizard makes two Microsoft SQL Server Analysis Services databases equivalent by copying the data and metadata from a source server to a destination server. This wizard can also be used to deploy a database from a staging server onto a production server, or to synchronize a database on a production server that has changes made to the data and metadata in a database on a staging server.

Apart from Data it copies the metadata, which makes Synchronization between different builds unsupported and you can’t synchronize across major versions or service packs.
