III.3.4 Testing
After the steps stated above, the migration to IPv6 is ready
to be tested. Comprehensive testing is required for application performance,
router/access device capacity and interoperability. It is recommended that all
testing be performed in an offline lab. This minimizes the impact on the
network during testing. Testing will provide also the documentation about test
results and will help us to analyze the QoS and performance of IPv6.
III.3.5 Deploying
In this study, we have not dealt with deploy step because it
requires to enable IPv6 applications and protocols and modification of the
entire network. Deploying network cannot realistically be done for several
reasons:
· Several types of router require a flash upgrade to
support larger IPv6 images or a memory upgrade to support the two concurrent
routing tables.
· Lack of IPv6 support from manufacturers for some
equipment. Some older equipment will never support IPv6.
III.3.6 Management
The final yet often forgotten step in the process is the
management. This step consists of any change in network. Change can be based on
some factors such as to add new equipment.
