Moving from one cloud platform to another is rarely simple. Whether it’s migrating from Google Workspace to Microsoft 365, or shifting data between file-sharing services, these transitions can disrupt access, change metadata, and even cause data loss. Though these cases differ from our usual work, we approach them with the same precision and evidence-handling standards. If a migration fails, digital forensics can help determine what happened, but only if the correct data is preserved.
Why Migrations Create Risk
Cloud migrations often involve bulk data transfers, account reconfigurations, and permissions changes. These actions can:
- Alter file timestamps or ownership records.
- Break links between files and metadata.
- Cause accidental deletions or overwrites.
- Temporarily open security gaps that can be exploited.
Even well-planned migrations can result in missing files, inconsistent data, or unexpected user access changes.
Common Forensic Challenges
- Metadata Changes: Platform differences can modify “created” or “last modified” dates, complicating timelines.
- Loss of Historical Logs: Some services do not migrate audit logs or file histories to the new platform.
- Overwritten Versions: Migration tools may replace existing files without retaining old versions.
- User Confusion: Employees may unintentionally move or delete data during the transition period.
Preserving Evidence During Migration
Before starting a migration, consider:
- Exporting and securely storing all available audit logs from the source system.
- Documenting file structures, permissions, and ownership before changes begin.
- Capturing snapshots of key user accounts and shared drives.
- Preserving cloud metadata alongside the actual files.
When Forensics Gets Involved
If a migration leads to suspected data loss or unauthorized access, a forensic team can:
- Compare pre- and post-migration logs to identify discrepancies.
- Analyze download, upload, and sharing events during the migration window.
- Trace unauthorized file access or copying to specific accounts or IP addresses.
