Internet protocol (IP) is considered a core protocol for every communication that performs worldwide. The world is considered as a big village due to the radical enhancement of communication. Due to the scarcity of IP addresses, low performance, a decline of a security, and reduction of reliability, IPv4 is becoming a deprecated protocol, and IPv6 was created by IETF to resolve those problems. Due to the incompatibility nature of the two protocols, IPv4 to IPv6 migration process has different factors for its success. An inadequate study has been done in previous research and it becomes an exciting domain for research. This study engaged Bunna International Bank S.C in the development of a migration framework by integrating different factors considered as a milestone for the transition process. The study follows a design science approach and performs one iteration cycle during the framework development. Data were collected from respondents via interview, observation, and document analysis. Throughout the collection process, high and middle-level management and field expertise are consulted to give their perception of IPv4 and IPv6 technologies. IT senior managers gave invaluable organizational level information on the IPv4 to IPv6 migration process. Besides to expertise interview, an observation was also performed by the researcher. The researcher had an opportunity to visit the head office, branches, data center, and disaster recovery site infrastructure network. Moreover, document analysis was performed by visiting relevant documents that assist the migration process. The proposed framework has pre-migration, migration, and post-migration phases. In each phase, a fragment of tasks is put that the organization should perform during the transition period. Additionally, the framework also introduces a hybrid migration model that fits the organizational infrastructure. Finally, the framework is simulated by the standard tool GNS3 and also evaluated by a domain expert using ISO/IEC 25010:2011 quality model. Thus, the result exposes that the proposed framework can assist in the transition of BIB’s infrastructure from the legacy protocol (IPv4) to IPv6.
