Map dependencies across layers
Capture application-to-application calls, databases, file transfers, identity services, batch schedules and network dependencies. The goal is to identify what moves together and what requires a transition arrangement.
Separate technical move from operating change
A workload may be able to run in a new environment while its monitoring, backup, access and support practices are still undefined. Plan these operational elements as part of the migration.
Sequence around business risk
Group work by dependency and business criticality, not simply by infrastructure category. A lower-complexity workload can provide learning before a critical integrated process moves.
Practical example
Example: a scheduled file exchange
A file transfer may rely on a legacy server path, service account, firewall rule and downstream batch window. Missing any one dependency can interrupt the process after migration.
Best practices
Put the fundamentals in place.
- Validate the inventory with application owners and operations teams.
- Document identity, network and scheduled-job dependencies explicitly.
- Rehearse cutover and rollback for workloads with critical process impact.
Frequently asked questions
Why is a server inventory insufficient?
It rarely captures the integrations, identities, scheduled work and operational practices that make an application usable.
Should all connected workloads move together?
Not always. The dependency map helps determine which can move independently and which require a planned transition.
