Planning
Change planning identifies the risk level that is associated with a change, and builds change
planning requirements to ensure a successful change. The main steps for change planning are
to:
●
Assign all potential changes a risk level prior to scheduling the change.
●
Document at least three risk levels for:
- Software and hardware upgrades
- Topology changes
- Routing changes
- Configuration changes
- New deployments
Assign higher risk levels to nonstandard adds, moves, or changes. The high-risk change
process that you document must include laboratory validation, vendor review, peer review,
and detailed configuration and design documentation.
●
Create solution templates for deployments that affect multiple sites. Include information
about:
- Physical layout
- Logical design
- Configuration
- Software versions
- Acceptable hardware chassis and modules
- Deployment guidelines
●
Document your network standards for:
- Configuration
- Software version
- Supported hardware
- Domain Name System (DNS)
- Device naming
- Design
- Supported services
