The workload
A Nigerian product team serves model predictions and needs to balance latency, model memory and request volume.
Load the same model and configuration on the target. Compare quality and latency on a representative evaluation set before directing user requests.
Inventory the source and destination
Record the ai inference services versions, data locations, access rules, scheduled jobs, integration endpoints and domain records. Confirm capacity and software compatibility on the destination. Keep the source recoverable until the destination has passed the agreed checks.
Load the same model and configuration on the target. Compare quality and latency on a representative evaluation set before directing user requests.
Rehearse before the live cutover
Preserve model identifiers, deployment configuration and required private artefacts. Track licences and provenance, and protect any retained customer inputs.
Make a trial copy to an isolated target and run this acceptance check: The deployed model meets an explicitly measured latency and quality target on the team's own evaluation examples. Disable or redirect customer-facing notifications, payment actions and scheduled jobs during rehearsal so testing does not duplicate live work.
Control the final writes
Choose a documented write-freeze or synchronisation procedure suited to the application. Assign one person authority to begin the cutover. Track the final successful copy, the point when new writes are allowed and the single system responsible for background processing.
Validate traffic and business records
Check model memory, batch size and tail latency after the move, together with counts or reference records that demonstrate data consistency. DNS caches may continue sending some clients to the old endpoint, so observe both systems during the transition instead of assuming a record change is instant.
If the destination fails the business check, investigate the workload-specific failure path: Check GPU-memory exhaustion, long inputs and queue time. Increasing batch size may improve throughput while making individual responses slower.
Define rollback before reopening
A rollback is straightforward only while the source still represents the authoritative data. Once the destination accepts writes, switching traffic back without reconciliation can discard new work. State the rollback deadline, the triggers and the procedure for preserving changes in advance.
For a Nigerian team, agree a maintenance window around actual working hours and customer demand. Verify access from the office and mobile networks, then retain the old environment according to a documented review and deletion schedule rather than an arbitrary promise of zero downtime.
Server migration worksheet
Use these prompts in your project notes. Replace general targets with measurements and an accountable owner.
| Decision | What to record |
|---|---|
| Workload cutover step | Load the same model and configuration on the target. Compare quality and latency on a representative evaluation set before directing user requests. |
| Authority during transition | One named environment accepts final writes and runs active jobs. |
| Validation evidence | The deployed model meets an explicitly measured latency and quality target on the team's own evaluation examples. |
| Rollback decision | Who decides, what failure triggers it, and how writes after cutover are reconciled. |
Can ai inference services move with no downtime?
That depends on the application, replication method and consistency requirements. A rehearsed maintenance window is often clearer than an unsupported zero-downtime promise. Estimate the final copy and validation time from a trial, then agree the interruption with the people affected.
