You can transfer your premium pass benefits to another save data via Transfer Pass Privileges.
Below are the benefits that can be transferred:
• Your progress toward premium missions
• Extra pack stamina added by the premium pass
Notes:
• Any premium tickets you have obtained, and cards and items you exchanged for at the shop cannot be transferred.
• If your premium pass subscription privileges were transferred to another save data, you will temporarily be unable to re-transfer them from that save data to another save data (including the original save data) for 60 days.
How to Transfer Pass Privileges
