You can’t migrate an expired domain. If you’re still within the redemption period to renew the domain by paying a higher fee, you should choose that (unless you believe nobody else will be interested in that domain name once it becomes available for anyone to purchase).

Once you renew the domain, there is an immediate 60-day (?) period when you cannot transfer the domain elsewhere. So you’d have to wait for that duration and then transfer. You won’t lose out on the expiration date though.

When you transfer the domain to another registrar, you’d have to pay a one year renewal fee, which will extend the ownership of your domain by one more year than what it was before.
