S3 to Google Cloud Storage Migration
Move object data from Amazon S3 to Google Cloud Storage, objects, buckets, IAM and lifecycle rules migrated via Storage Transfer Service with checksum verification and zero data loss.

Yes, you can migrate from Amazon S3 to Google Cloud Storage. Codimite, a Google Cloud Partner, uses Google's Storage Transfer Service to copy your S3 objects and metadata into Cloud Storage, maps IAM and bucket policies, re-creates lifecycle and storage-class rules, and verifies integrity with checksums, using bulk plus incremental sync so there is no downtime at cutover.
Why migrate
Competitive storage pricing and automatic discounts, plus a chance to consolidate storage where your compute and analytics already live.
Cloud Storage is the lake layer feeding BigQuery and Vertex AI, query and train directly on your data without moving it again.
Cloud Storage offers a single global namespace model with strong consistency and multi-region buckets.
One IAM, billing and security model alongside the rest of your Google Cloud estate.
Diversify object storage off a single provider.
What we migrate
| S3 object | Migrates to Cloud Storage | Notes |
|---|---|---|
| Objects & prefixes | Objects & folder paths | Storage Transfer Service; checksum-verified |
| Object metadata | Object metadata | Content-type, custom metadata preserved where supported |
| Buckets & regions | Buckets (region / multi-region) | Location and naming planned to avoid conflicts |
| Storage classes | Standard / Nearline / Coldline / Archive | Class mapping decided in design |
| S3 lifecycle policies | Object Lifecycle Management rules | Re-created, not copied verbatim |
| Bucket policies / IAM | Cloud IAM & bucket policies | Permissions re-mapped to Google identities |
| Versioning | Object Versioning | Enabled to match source where required |
Exact mapping of storage classes, lifecycle and permissions is confirmed during assessment.
Our process
We inventory buckets, object counts, data volume, storage classes, lifecycle rules and access patterns, and size the transfer.
We design target buckets, locations, storage-class and lifecycle mapping, IAM and the transfer method (network vs Transfer Appliance).
A representative bucket transfers first to validate fidelity, throughput and permissions.
Bulk transfer via Storage Transfer Service while S3 remains the source of truth, with incremental syncs.
Object counts and checksums are reconciled against source; access tested by applications.
Final delta sync, application cutover, lifecycle tuning and cost optimization.

FAQs
Yes, objects, metadata, IAM and lifecycle rules move to Cloud Storage via Storage Transfer Service, with checksum verification.
Storage Transfer Service copies objects directly from S3 over the network with verification and incremental sync; Transfer Appliance handles very large datasets physically.
No. Bulk transfer runs while S3 stays the source of truth, then incremental syncs and a final delta sync precede cutover.
They're re-mapped, S3 classes to Standard/Nearline/Coldline/Archive and S3 lifecycle to Object Lifecycle Management rules.
