Migration Plan
• Study the network and gather information on
network infrastructure, key network equipment,
servers, appliances and computers,
• Gather information on critical applications,
• Prepare plan to migrate to a dual stack IPv4/IPv6
network with minimal impact on existing critical
applications, and
• Prepare a set of strategies covering IT equipment
acquisition, new critical applications, manpower
resource planning and network policies to prepare
for IPv6 compliance audits based on Global
Standards

Migration approach
• Inventory of current IPv4 addresses and time to
address exhaustion.
• Identification of IPv4 assets including routers,
applications, servers and hosts.
• Complexity of existing IPv4 networks

Pilot Implementation
•
Approach for Large Organization
1. High cost of Migration
2. Up-gradation of hardware and software
3. High cost of application software migration
•
Approach for Small to Medium Sized
Organization
1. Medium or low cost of Migration
2. Cost can be reduced if hardware, software upgradation is done thru regular upgrade cycle
IPv6 Test bed for large organization
• Creates scaled version of the network in
an isolated and controlled environment.
• Test bed must have
– Flexibility
– Isolation
– Partnership
– Interoperability
– Network

IPv6 Training
•
•
•
•
Benefits of IPv6 especially to the organization concerned.
Technical specifications of IPv6.
Transition mechanisms available as well as their pros and cons.
Routing schemes and algorithms and how do they differ from
IPv4.
• Security benefits i.e. IPSec; its uses, benefits and how to set it
up.
• Security considerations having both IPv4 and IPv6 on the
network.
• Understanding risks that may have cropped into the upper layer
protocols due to bugs introduced in them during the porting.

IPv6 Compliance and Certification
• New procurement of ICT equipment must be
IPv6 Ready
• Compliance test of products on conformance to
the standards set by the IPv6 Forum.
• Organization and Solution providers may work
jointly sharing the responsibilities

IPv6 Audit
• Objective
– The audit’s objective is to produce an
unbiased validation of the IPv6 self compliant
status based of the nine suggested RFCs.
– To provide consultation on the deployment of
IPv6 networks for future setup.

IPv6 Audit
• Decision to be taken
– Identify any changes that may be needed to
our network infrastructure.
– Identify hardware used and their level of
support of IPv6.
– Review existing network diagram to better
plan IPv6 deployment.

Migration Roadmap
•Check IPv6 compliance:
Study the existing network
 Recommend upgrade of the equipment
Software upgrade or hardware upgrade/replacement.
All future equipment purchase must ensure that the equipment is
IPv6 ready
•Plan IPv6 addressing:
Take IPv6 addresses from APNIC or ISP. Make IPv6 Address
allocation policy and plan IPv6 addressing for the entire network.
•Enable IPv6 routing:
Configure all Layer 3 switches and routers
Enable static/dynamic routing inside the network.
34
Migration Roadmap
•Setup IPv6 Application Servers:
Upgrade the Domain Name servers
Upgrade web servers, mail servers, network management servers
•Enable IPv6 peering:
Enable BGP (Border Gateway Protocol) routing for IPv6 peering
with ISP to provide Internet access over IPv6.
•Migrate Services on IPv6:
Test services like Internet access, Email, VoIP, IPTv etc. on IPv6
and migrate the services to support both IPv6 and IPv4.
