Agent-based replication mirrors the source disk incrementally. Cutover creates an ECS instance from the latest mirror.</li>\n<li>DTS supports full data migration followed by incremental sync for: MySQL, PostgreSQL, Oracle, MongoDB, and Redis. Real-time sync can maintain near-zero lag for continuous replication. DTS lag monitoring is critical during incremental sync — cutover should only proceed when lag &lt; 5 seconds.</li>\n<li>OSSImport is a migration tool for bulk object transfer from S3/Azure Blob/HDFS/local to OSS. Supports checksum verification and incremental sync.</li>\n<li>Cutover sequencing rule: database cutover carries the highest risk — always migrate data first, verify integrity, then cut DNS/LB last. Reversing this order risks data divergence.</li>\n<li>DTS replication user on source MySQL/PG requires <code>REPLICATION SLAVE</code> + <code>REPLICATION CLIENT</code> privileges. Applying least-privilege means granting only these, not <code>SUPER</code>.</li>\n<li>Always verify backup integrity before any cutover — if the backup is untested, the rollback path does not exist.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Prefer official Alibaba Cloud documentation and live evidence over memory or inference.</li>\n<li>Separate confirmed facts from inference. If DTS lag rate, SMC replication status, or backup integrity was not verified, say so.</li>\n<li>Challenge cutovers without tested backups, DTS lag above 5 seconds at cutover time, missing go/no-go criteria, and overprivileged DTS replication users.</li>\n<li>Keep answers scoped, reversible, and explicit about sequencing risks and open questions.</li>\n<li>Load references only when needed; do not pull all deep guidance into short answers.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when designing the full migration plan, cutover sequence, or formatting the final answer.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud SMC or DTS service behavior or checking the detailed source list.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the scoped target and evidence level,</li>\n<li>the migration tool selection and configuration assessment,</li>\n<li>the cutover sequencing plan with go/no-go criteria,</li>\n<li>the rollback path for each phase,</li>\n<li>the DTS lag monitoring and backup verification status,</li>\n<li>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":895,"isText":true},{"path":"references/official-sources.md","sizeBytes":570,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1593,"isText":true},{"path":"SKILL.md","sizeBytes":3811,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
