Data Center Migration Decision Log
This is a practical guide to building a decision log for a data center migration project — a record of the key decisions made, by whom and why, adapted to the realities of relocating or consolidating data-center infrastructure.
What a Decision Log is
A decision log is a record of the key decisions made, by whom and why. For the full concept and how it works in general, see Decision Log. On a data center migration project it plays the same role, tuned to this kind of work.
Why it matters for a Data Center Migration project
Data Center Migration projects live or die on relocating or consolidating data-center infrastructure. A well-built decision log gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how data center migration projects drift into avoidable delay and cost.
What to include
- Decision
- Date and owner
- Rationale
- Alternatives considered
- Impact
Data Center Migration-specific considerations
Tailor the decision log to the risks that most often derail data center migration projects:
- Application dependency mapping
- Migration-window downtime
- Hardware and network cutover risk
Example
On a real data center migration project, the decision log would be shaped by relocating or consolidating data-center infrastructure. In particular, it should explicitly account for the project’s biggest risks — application dependency mapping, migration-window downtime, hardware and network cutover risk — rather than treating them as afterthoughts.
