Block vs. File Level Cloud Migration

RiverMeadow is the only Cloud Migration solution that offers both block-based and file-based migration capabilities. Both have their own merits depending on the use case at hand. To enforce only one migration method to suit all migrations would be akin to having one hammer to solve any household repair.

So what are the differences between them and when would they be best suited, depending on your needs?

Why use Block-based? 

Block level migrations provide an exact copy of data from Source to Target machine. Block truly defines the Lift and Shift paradigm. 

When to use Block-based?

  • When the goal of the migration project is to quickly lift and shift workloads from source environment to target Cloud
  • When performing live migrations of Database and Message Queue related application workloads. Block migrations leverage an Application Consistent snapshot to facilitate live migration without concerns of open files.

Why File-based?

File level migrations offer greater flexibility of what data to copy from Source to Target machine. File allows for transformation of the workload during migration which we call Lift and Evolve.

When to use File-based?

  • When the goal of the migration is to refactor the Target machine. This would include modifying the partition mapping or file system type on Target.
  • When the goal of the migration is to resize disks or filesystems on the Target machine. This transformation method can reduce costs on target Cloud.
  • When the goal of the migration is to only migrate selective bits (Drive Letter, Mount Point, Folder) of data to the Target machine. This would include use cases to split or merge data from different Sources to the Target machine.
