Migration Couchtuner

CouchTuner originally launched in 2011 as a content aggregator, providing links to third-party streaming servers like Putlocker. Because it indexed copyrighted material without authorization, it quickly became a target for the Digital Millennium Copyright Act (DMCA) and major film studios.

| Category | Recommendation | |---|---| | | Keep JSON documents shallow (< 5 KB) to maximise bulk‑load throughput. | | Index Strategy | Re‑create indexes on target before the final cut‑over; use “covering” indexes to avoid full‑scan verification. | | Network Planning | Ensure at least 1 Gbps dedicated link between source data center and cloud region; enable TCP‑BIC for large bursts. | | Backups | Take a full snapshot 24 h before migration; retain it for 90 days as a rollback baseline. | | Testing | Run at least one “cold‑run” on a copy of the source data (≤ 5 % of production size). | | Observability | Set alerts on: (a) replication lag > 30 s, (b) error rate > 0.1 %, (c) target CPU > 80 % for > 5 min. | | Compliance | Verify that the target region satisfies GDPR/CCPA requirements; enable server‑side encryption at rest. | | Rollback | Keep source read‑only for at least 48 h post‑cut‑over; maintain a reversible DNS entry. | migration couchtuner
