How to Find an Application’s Dependency on Local File Storage Before Migration

An application can appear stateless while quietly storing uploads, generated reports, or session data on a local server disk. After migration to multiple replaceable instances, users may see missing files or inconsistent behavior if each instance has a separate filesystem.

Review application configuration, code paths, scheduled jobs, and server directories that change over time. Ask support teams where users expect documents to appear. Check whether files are shared between workers or included in backups.

  • Classify temporary files separately from customer records.
  • Choose shared object or file storage for durable content where appropriate.
  • Preserve access controls and lifecycle needs during transfer.
  • Test upload, download, background processing, and recovery after migration.
