The paper presents an introduction to challenges and security issues faced while migrating from IPv4 to IPv6.The depleting IPv4 address space and its inability to meet new requirements of internet has made this migration inevitable. Ipv6 has many distinguishing features which qualify it as a replacement of Ipv4.The process of shifting is not hurdle free and can be a threat to security of networks if proper care is not taken throughout the installation process. Several strategies have been proposed and implemented to speed up the process of transition and make it smooth and secure. Dual stacking and encapsulation are the two most widely used migration techniques.
