Database Migration to Managed Services
Databases move to a managed service with as little downtime as their owners allow: copied in full, kept in step, then switched by name.
The cloud's migration service copies each database to a managed service while the apps keep using the old one: a full load first, then every change as it happens, over the private link. At cutover the apps pause, the last changes land and a DNS name points them at the new database, which runs with a standby in a second zone, backups to any point in time and its own monitoring. Where the engine changes, the schema and code are converted first.
Point at a component to light its links; select it for what it does here and the practice that makes it right on AWS.
When to use it
- PostgreSQL, MySQL, SQL Server or Oracle databases the customer still patches, backs up and fails over by hand
- Owners who allow a short cutover, too short to copy the data while the apps are stopped
- A new version or a new engine that end of support or licence terms call for
Where FleziLift fits
The AS-IS assessment grades each database's version, size, edition and extensions by evidence level (L0–L3), and the 7R rule tree sends it to the target design's managed service with its readiness and risk, or keeps it on a VM where that service cannot run it. The Wave Plan keeps each database in the same move group as the apps that use it and takes every cutover through gates at −28, −21, −14, −7 and −1 days, on the day and at +3; Go / No-Go decides by eight written rules. The playbook names the cloud's own migration service for each task: the copy itself runs in those tools, not in FleziLift.
