That is a tad optimistic. They give by default 3 months of notice for transfers, and you can't apply until the end of the training. Keep also in mind that you have a windows of 2 weeks every three months at fixed date when you can apply. You could get lucky, but I would not bank on 4/5 months. Plus it depends on the time of joining, they are not likely to give you a transfer during summer.
Most of the transfers normally happen after October and up until March/April.
