there has to be a way to transfer
Nope, there does not. Getting convicted in CA is very little different than getting convicted in France. France wouldn't have to let you leave the jurisdiction, and neither does CA.
Most all or all states are joined in an "interstate compact" to allow transfers of probation. It requires agreement from CA, and agreement from the state you want to move to.
With the state of CA's budget, I'd think they'd be more than happy to let you go. However, with the likely state of the budget in FL, they likely don't need anybody else on probation. Things are tough all over.
Call the attorney that represented you. If you had a public defender, call him or that office. In my state, a PD would continue to represent you for certain matters even after sentencing.
