A sim swap is literally just swapping from one sim to another which isn't necessary going from an 8 to an 11.
Just use your old sim.
To transfer data you either need to tap to allow a direct data transfer when setting up your 11 or backup your 8 to itunes and then restore that backup to the 11.
You can also just login on the 11 and restore from iCloud but that could take a long time if you have a lot of data and only do this over a wifi connection.
