Stop in for a cup of coffee

If you're an Appler, can't you use the "swap phone" function in settings and back up your data in the iCloud?
Don't want to use the cloud thanks. I think I'll try to back up onto local home PC. I hate it that my work phone asks me for my Apple ID, that's not for sharing with work devices imo. Just hoping the swap doesn't take half the day but with all the security and applications, RSA tokens etc. on that phone it likely will.
