Default Copy WhatsApp tot another phone?

Hello,

my Xperia Z cracked so I bought a Nexus 5.
I use whatsapp a lot and I want it installed on my Nexus 5 but in order for it to work I need to send a text tot my phone. the problem is that my new sim will arrive in 2 weeks. Can I somehow copy whatsapp from my Z tot my Nexus and keep it the same as I left it on my Z, andere skip the verification? both are rooted. I tried titanium backup and copied the files from my Z tot the Nexus and tried tot install it, but I got an parse error or something?

thanks in advance!
