Verizon device switch question

I have an iphone 4S, with unlimited data, hubby has the 4 with a 2GB data plan. I transferred my upgrade to his line and ordered a 5. I plan to switch so his 4 to my line, activate the 5 on his line, and then switch so he keeps the 4 and I get the 5. Will this work? Anything I need to know about trying this??? I'm assuming when switch the 5 to my line after activation is when I might have trouble?

 

Thanks but that's not really helpful, I've looked on the Verizon site and I can't find any rules on switching devices.

I know the 5 has a nano sim, but it doesn't tell me if I'll need to have another nano sim to switch it to another line. I've read in one place that you have to wait 24 hours between switches and in another that you don't. I was hoping someone had experience with this.

 

Just to follow up, for anyone else who may have the same question, this did work fairly easily.

I activated the 5 on my husbands line. Then on my line was able to make his iphone 4 active. I tried doing a device switch online to move the 5 to my line and the 4 back to his, the system was going to allow the change but I did need a new nano sim card. Verizon was going to mail me one for free but I didn't want to wait from Saturday to Monday. (Yes I know, I have no patience ) To avoid a 30 minute drive to a Verizon owned store, I took the phones to a 3rd party Verizon store and asked if they could switch them for me. I was told I would be charged $10 for the sim card, but they could! It didn't force me to change my plan, so all is well in my world. Changing to the share everything plan would have cost $20 more a month and data would have been limited.
