AWS published an end-to-end pattern for Database Migration Service change data capture from self-managed SQL Server without granting the endpoint login sysadmin. It uses certificate-signed wrapper procedures, per-replica setup for availability groups, Secrets Manager and customer-managed KMS keys. The underlying development was published October 6, 2026; AI Speed is publishing this analysis on October 7 and keeps those dates separate.
Canadian organizations migrating regulated records should test cutover, reconciliation, encryption and regional destinations with production-like volumes. The endpoint account and migration logs should not expose more data than the replication task requires. This account distinguishes product documentation, tutorials and event plans from independently established outcomes.
What the source establishes
AWS published an end-to-end pattern for Database Migration Service change data capture from self-managed SQL Server without granting the endpoint login sysadmin. It uses certificate-signed wrapper procedures, per-replica setup for availability groups, Secrets Manager and customer-managed KMS keys.
The linked primary source supports the narrow description above. Product capabilities, performance statements and expected benefits remain attributable to the publishing organization unless an independent source with a disclosed method verifies them.

What it does not establish
Least privilege narrows authority but makes configuration and renewal more complex. Missing a replica, certificate permission or wrapper procedure can interrupt replication. The guide does not prove zero data loss or suitability for every SQL Server topology.
A release page, architecture diagram or polished demonstration is not a reliability result. A useful evaluation records the exact version, representative inputs, permissions, failures, review time and the baseline it replaces.
Why it matters in Canada
Canadian organizations migrating regulated records should test cutover, reconciliation, encryption and regional destinations with production-like volumes. The endpoint account and migration logs should not expose more data than the replication task requires.
Availability, price, privacy terms, data location and support can vary by country, account and sector. Test English and French where relevant and retain accountable human review for consequential actions.
What to watch next
Watch for documented rollback, certificate rotation and behaviour during failover. A migration sign-off should reconcile counts and critical fields rather than relying only on a healthy service status.
AI Speed will revise this story if completed outcomes, independent tests or corrected documentation materially change the evidence. Until then, the update should be read at its documented stage.
