Unfortunately, you can't transfer pixels from disabled Facebook ad accounts - they're permanently tied to the original account. However, here's what you can do: create a fresh pixel in your new account through Ads Manager → "Events Manager" → "Add Data Source" → "Facebook Pixel."
To recover tracking data, export any audience lists from Business Manager before the account was fully disabled. You can rebuild Custom Audiences in the new account using email lists or phone numbers you collected.
For future protection, always set up Facebook Conversions API alongside your pixel - it provides backup tracking and better data resilience. I've seen many advertisers successfully rebuild their tracking within 2-3 weeks using exported customer data.
How long ago was your account disabled, and do you still have access to customer email lists to rebuild your audiences?
