“Lessons Learned”(or what we might have done differently)

• Moving the PBX connectivity sooner (close to the 50% conversion mark).

• Start planning moves with vendors earlier (and allow more time for slips)

• Beware of the “extended NOC!”

• Inclusive cost models (licensing for all components, including ongoing maintenance costs).

• Work disaster recovery plans in early.

• Carefully consider your deployment options (forklift or phased?).

• Do not forget legacy application support issues (e.g., analog).
