Now that we have completed the planning, below are some of our Best Practices for carrying out the migration based on our experience.
|
|||
|
|
|
|||
|
|
First, it can help to break the migration down into an order of activities, for example:
|
|||
|
|
|
|||
|
|
* **Minimum Viable Product (MVP) launch**
|
|||
|
|
* Platform implemented, passed security/change management requirements, and available for developer use
|
|||
|
|
* Rollout to the highest priority groups of users
|
|||
|
|
* Matching use cases of the legacy platform
|
|||
|
|
* Legacy system fallback available
|
|||
|
|
* **Medium-term**
|
|||
|
|
* Rollout to additional groups; adoption of further, less critical use cases
|
|||
|
|
* Sunset of legacy system
|
|||
|
|
* **Longer term**
|
|||
|
|
* Adoption of new use cases
|
|||
|
|
|
|||
|
|
For each activity, plan for the Level of Effort (LoE), or the number of hours/days the task will take the assigned resource or group to fulfill.
|
|||
|
|
|
|||
|
|
Next up is risk handling. **Are there any perceived risks to the timelines that could be addressed upfront?**
|
|||
|
|
|
|||
|
|
* Have the teams involved with the migration committed to set hours for working the migration tasks upfront, have had migration project success criteria and their tasks communicated to them, and Q&A fulfilled?
|
|||
|
|
* How long are various sign-offs by any relevant groups expected to take?
|
|||
|
|
* E.g. Change Advisory Board, Security Controls, hardening checks, etc
|
|||
|
|
* Plan to exceed each team’s documentation requirements to ensure fewer Requests for Information
|
|||
|
|
|
|||
|
|
Every step of the way, it can help to conduct reviews and look-backs at each rollout stage as well as what lies ahead.
