How to swap memory in Sony Xperia C 2305?

I watched a lot of videos and read about replacing memory on android devices.
But this model (Sony Xperia C 2305) is different in that the phone's memory first contains the device's memory, then the sd card and then the internal memory.
In general, when I swap sdcard0 to sdcard1, it turns out that the memory of the sd-card changes with the internal memory, and this is of no use at all.
Who knows how to change the memory of a device with sd-card memory on this model?
