Adds a manual, operator-facing guide for migrating an existing single-server Platforma instance (standalone binary or Docker image) onto Kubernetes on AWS using this Helm chart.

Location: infrastructure/aws/migration.md, alongside advanced-installation.md.

What it covers:

  • Plain-language overview and the recommended minimal-downtime flow: sync primary storage live → short cutover (consistent DB backup + delta sync) → Helm install → cache invalidation.
  • Full step-by-step procedure: freeze the source, cancel running blocks (--cancel-running-blocks), two backups (pre-cancel safety backup of the old instance + consistent migration dump), primary-storage copy via S3 Batch Replication or in-cluster s5cmd, IRSA service account, DB download/restore, Helm install, post-install cache invalidation, verification, rollback, and cross-account sync.
  • All commands and YAML manifests are in fenced code blocks so they can be copied and pasted directly.

Documentation only — no chart or template changes.
