Hey @Wiizzyy
I am afraid that there is no way to merge two different accounts and move your account progress from one account to another.
If you unlink your Xbox profile from your previous account and link it with a new EA profile, that will reset your account progress. There is a warning you need to accept before completing these steps, and we have it explained here on our website. Account Unlinking Risks
*If you unlink your platform account and link it back to your original EA Account, you may be able to get your stuff back if you still can access the account.
For more information, please check out our quick guide to Apex Legends Cross Progression.
Feel free to contact our support team if you need help with your account changes.
