The context
In this illustrative scenario, a company stores documents, exports and application files on Amazon S3. Volumes are growing, but usage varies: rarely accessed archives, daily exchanges and content served to applications. The team wants a clearer storage foundation without changing every part of its infrastructure at the same time.
The problem to solve
Invoices combine capacity, requests and transfers. The dependency inventory is incomplete, and a rushed move could interrupt some user journeys. Any egress charges from the original provider also need to be included in the migration budget from the initial planning stage.
The proposed mission
- 01
Map buckets, volumes, access patterns and the S3 functions actually used to identify an initial transferable scope and the changes needed within the applications themselves.
- 02
Test transfer tools and compatibility on a representative sample, then verify integrity, access rights and performance before deciding how to sequence the successive migration batches.
- 03
Prepare the cutover with the team, monitor discrepancies and plan an appropriate rollback, then document the target operating model and the conditions for deleting old copies.
Intended benefits
- More predictable storage costs, with no egress or API fees at Mintera.
- A documented migration path, with explicit stages, responsibilities and decisions along the way.
- Better visibility into application dependencies and the options for future hosting decisions.
How to measure the outcome
- Total monthly storage cost
- Volume migrated with verified integrity
- Application incidents during cutover
The baseline and objectives are defined during scoping, then compared with pilot results.
