To repeat information between units, you want the next:
- Sufficient area on the gadget you might be copying to (equal to or better than what you might be copying from).
- Sufficient ‘working’ area on the units in order that the recordsdata may be copied and the system can operate (that is typically about 20%.)
Query 1, “Will I be capable of use the cellphone’s full capability” – sure. Assuming your iPhone 14 Professional Max has sufficient free area, you may completely copy the entire information out of your iPhone 13 mini. Afterwards, no matter area is left over (about 150GB, based mostly in your numbers), will stay free on your use.
Query 2, “After the switch” – after the information is copied, there will likely be TWO copies of it (one on the previous cellphone, one on the brand new). The previous cellphone won’t routinely be cleared (you might be copying the information, not shifting it.) Nevertheless, as soon as the information is all in your new iPhone 14 Professional, you’ll free to reset/erase the previous cellphone and use it for no matter different issues you prefer to.
