Islam and Catholicism
The question as posed is nonsensical. A person in a more expansive religious group cannot convert to a smaller group within that religion. Ismaili Islam is one form of Shiite Islam. The equivalent question in another religion would be "How can a Christian convert to Catholicism?" or "How can a Theravada convert to Buddhism?" If a non-Ismaili Muslim (such as Sunni, a Zaydi Shiite, a Twelver Shiite, an Ibadi, etc.) wants to join Ismaili Islam, all they need to do is find an Ismaili congregation and join their community.
