For most enterprises, the biggest challenges of a large migration are organizing the people and processes required to accomplish this task. This typically involves organizing people from many different teams that have competing priorities. You must align your organization to the same goals and form a cross-functional large migration team. A migration team can be entirely internal to your organization, or it might include AWS Professional Services, AWS Partners, or other third-party consultants. This team must be empowered to meet regularly in order to plan and cut over your migration waves according to your migration forecast. Building a strong governance model for your large migration project helps the migration team to effectively track migration activities, follow a set of identified processes, and establish an escalation mechanism when obstacles are not addressed.
