Accelerate and Automate Migrations
Run a migration as a coordinated fleet of builders, testers and reviewers, with durable progress and your own workflow in charge.
Migrations fail slowly. The first modules go well, then the work outlasts the team’s attention. People rotate, the source system changes, and eighteen months later nobody is certain which modules are verified and which were quietly skipped.
A large migration needs a repeatable way to translate, test and review each part while keeping the overall programme moving. Lightspeed supplies durable agent sessions and delegation for that work.
Build a factory around each slice
A planner reads the map of the source estate and breaks the migration into slices: a batch chain, a service, a schema domain.
Builders implement the change in prepared environments. Testers run the existing suite and new checks. Reviewers examine the changes with fresh context and return their findings. The planner brings the results together and sends incomplete work back for another pass.
Profiles define each specialist’s role, tools and resources. The same process can be repeated across modules while delegation limits control how much runs at once.
Keep progress beyond the conversation
Sessions record their progress and recover after worker restarts. Workspaces hold source notes, test reports and decisions so the team can return to them throughout the programme.
This is especially useful when work pauses for a change freeze or a dependency. The project retains its conversations and evidence without requiring a dedicated running machine for every waiting agent.
Execution machines can be prepared for the next stage and retired after useful outputs have been saved.
Compare approaches before committing
Some decisions deserve two attempts: rewrite or transpile, keep the batch window or move to events, replace an interface or preserve it.
Give two teams of agents the same source snapshot and discovery report, with separate workspaces and machines. Compare their test results and reviews. The alternatives begin with the same evidence, and the programme keeps a record of why one was chosen.
Make verification part of the process
The migration’s existing tests and acceptance criteria remain central. Agents can produce changes and investigate failures; test results and review determine whether a slice is ready.
Lightspeed’s evaluation harness also lets the team check representative agent tasks when prompts or tools change. A better translation procedure can be tried on a small set of cases before it is used across the remaining estate.
Keep the programme’s workflow in charge
An existing Temporal workflow can start managed sessions, expose the business operations they need, and collect their results. It can wait for tests, request human approval and decide when a slice advances.
That keeps sign-off connected to the reports and changes being reviewed. The programme office sees progress through its own process, while agents handle substantial work within it.
The benefit grows through repetition: one well-understood slice becomes a repeatable way to work through the next hundred.
