Final answer:
During the Moving to Magenta Experience, the voicemail password and greeting do not transfer over.
Step-by-step explanation:
When completing the Moving to Magenta Experience two features that will NOT transfer over are the voicemail password and the voicemail greeting. These features are specific to the previous carrier and will need to be set up again once the transfer is complete. Other features like call forwarding, caller ID and contacts should transfer over smoothly.
