This is the foundation for all subsequent stories. + +**Independent Test**: Can be fully tested by running `docker compose up` on the new host and verifying all containers are healthy via `docker ps` and health check endpoints. + +**Acceptance Scenarios**: + +1. **Given** a fresh OS installation on the new host, **When** the administrator runs the provisioning script, **Then** Docker Engine and Docker Compose are installed and verified with `docker --version` +2. **Given** Docker is installed, **When** the administrator mounts the ASUSTOR CIFS share, **Then** `/mnt/uploads/temp` and `/mnt/uploads/permanent` are accessible and writable by containers +3. **Given** CIFS mounts are ready, **When** the administrator runs `docker compose up -d`, **Then** all 7 service containers start and report healthy within 5 minutes +4. **Given** all containers are running, **When** the administrator checks network isolation, **Then** Ollama and OCR Sidecar ports are NOT accessible from LAN (only Frontend port 3000 and Backend port 3000 are published) + +--- + +### User Story 2 - Migrate Data from QNAP to New Host (Priority: P2) + +Database administrator migrates MariaDB data and Elasticsearch indices from QNAP to the new host, ensuring zero data loss and minimal downtime. + +**Why this priority**: Data migration is the critical path for cutover.

System must have swap space configured and memory limits per container. +- **CIFS mount failure**: What happens when ASUSTOR NAS is unreachable? File upload/download will fail; system must degrade gracefully with clear error messages. +- **Single host hardware failure**: What happens when the new host crashes? SPOF mitigation requires backup data on QNAP and a disaster recovery plan. +- **Network misconfiguration**: What happens if Docker bridge network is accidentally exposed? Sidecar and Ollama would be accessible from LAN, breaking the security model. +- **Database migration partial failure**: What happens if MariaDB migration fails midway? Rollback plan must restore QNAP as the active database host. +- **Elasticsearch index corruption during migration**: What happens if ES indices are corrupted during transfer? Re-indexing from MariaDB data must be available as a fallback. + +## Requirements _(mandatory)_ + +### Functional Requirements + +- **FR-001**: System MUST co-locate all 7 services (Ollama, OCR Sidecar, Backend, Frontend, Redis, MariaDB, Elasticsearch) on a single Docker host with a unified `docker-compose.yml` +- **FR-002**: System MUST use ASUSTOR (192.168.10.9) as the primary NAS for file

MUST retire Desk-5439 after cutover is verified stable for 24-48 hours +- **FR-013**: System MUST provide a rollback plan to restore services on QNAP and Desk-5439 if the new host fails +- **FR-014**: System MUST verify all core DMS functions (login, document CRUD, OCR, AI inference, search) work end-to-end on the new host before decommissioning old hosts +- **FR-015**: System MUST monitor RAM and VRAM usage for 24-48 hours post-cutover to detect resource pressure + +### Key Entities _(include if feature involves data)_ + +- **Docker Compose Stack**: Single `docker-compose.yml` defining all 7

**SC-001**: All 7 service containers start and report healthy within 5 minutes of `docker compose up -d` on the new host +- **SC-002**: Database migration completes with 100% row count parity between QNAP and new host for all critical tables +- **SC-003**: Elasticsearch migration completes with 100% document count parity between QNAP and new host for all indices +- **SC-004**: Core DMS operations (login, document upload, search, OCR, AI inference) complete successfully on the new host with zero functional regressions +- **SC-005**: Ollama and OCR Sidecar are unreachable from LAN (port scan returns closed/refused for ports 11434 and 8765) +- **SC-006**: Backend-to-Ollama latency is reduced by at least 50% compared to cross-host LAN communication (measured via AI inference response time)
