Switch a Q10 with a Classic and vice versa, how can I do this?

Hi,

I'm currently using a Classic and I want to give it to a Q10 user, so he can test the device and decide if he likes it. For this, I have to transfer my data to the Q10 and the Q10's data to the Classic. What should I use for this, normal backups or BlacBkerry Device Switch? I don't want to use 3rd party apps.

Get Ultimate Backup for BlackBerry 10 from BlackBerry World. You will not want to use anything else.
