Hey @karter8523,
Apex Legends does not currently support cross-progression, so I'm afraid there is not a way to transfer progress from one platform to another.
While that's something being worked on, we don't have any particular details on what that will eventually look like, though it will likely help to have all your platforms under the same EA account when that time arrives.
You can check out this page for more information on linking an account to make sure they're attached to the same EA account for the future. Note that unlinking an account will cause progress to be lost, however. If you're just looking ahead to get ready this may help out, however if you already have substantial progress on both separate accounts you'll likely not want to go through those steps.
