How to Migrate a Cloud Application That Uses a Shared Object Storage Bucket

Multiple applications may share one object bucket for uploads, exports, and static assets. Moving only one workload can change permissions, path assumptions, lifecycle rules, or encryption access for the others.

What to check

Map bucket consumers, prefixes, roles, event notifications, lifecycle policies, encryption keys, and public access settings. Identify which systems write and read each prefix and verify cross-account permissions.

Recommended next step

Plan migration boundaries per consumer or prefix, test read and write behavior from the target identity, and preserve object versioning and audit logs. Remove old access only after all dependent workflows have moved.
