Question
If a sunni wanted to become a shia and vise versa, what ceromonys would be employed? Would they have to recite the Muslim creed again?

Answer
Bro!
Conversion from Sunni to Shia is NOT allowed in Islam. Because Shia are Non-Muslim according to many great scholars. The main reason for declaring them non-Muslim is that they have polytheist beliefs and they worship, Ahlul-Bayt.
see a good example here (that how shia twist the verses of Holy Quran and their worship of Ahlul-Bayt) at:

Plus some of the Shias' or Shiites' mosques are blasphemous mosques according to the Noble Quran!
see here

so conversion from Sunni to Shia is NOT allowed according to Islam.

Conversion from Shia to Sunni is ALLOWED in Islam and you have to convert just as a non-Muslim converts to Islam because previously you had polytheist beliefs and you were no more different from a non-Muslim. So your method of conversion will be just like a non-Muslim.

If you still have confusion please feel free to ask me again. May Allah give you the right path.

God Bless You.
