How to migrate legacy apps without creating a blip on the customer’s radar?
As a new engineer on a team - how to contribute to system modernization by migrating legacy apps without creating a blip on the customers radar?
The answer is use-case dependent and very contextual.
But here are a few generic tips.
Perform the migration in stages.
Rather than attempting to migrate all of the legacy applications at once, break the process down into smaller chunks.
One service at a time?
Benefits - every stage can be tested thoroughly. Rollback is easier.
If this is already not a practice, recommend and establish one.
This involves creating a copy of the legacy app and its associated infra, and then directing traffic to the new version once it is ready.
Benefit - zero downtime
Transparent communication with stakeholders/customer
Provide regular updates, build and ensure that your customers feel confident in your ability to handle the migration smoothly
Finally - test like your life depends on it
