Migration Plan

04/19/23 3

• 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

Migration Options

• Approach for Large Organization1. High cost of Migration2. Up-gradation of hardware and software3. High cost of application software migration

• Approach for Small to Medium Sized Organization1. Medium or low cost of Migration2. Cost can be reduced if hardware, software up-

gradation is done thru regular upgrade cycle

Pilot Implementation

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

04/19/23 7

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 Compliance and Certification

04/19/23 11

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.

04/19/23 12

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 Module

• Different methodology for Large, medium and small organization

• Training

• Joint working of service providers and organization

Migration Roadmap

34

•Check IPv6 compliance: Study the existing network Recommend upgrade of the equipmentSoftware 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 routersEnable static/dynamic routing inside the network.

Migration Roadmap

35

•Setup IPv6 Application Servers: Upgrade the Domain Name serversUpgrade 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.
