Linode migration with cPanel

Hello Linodions, I have a question i hope someone can give an answer to.

I want to migrate my linode to London, however i have cPanel installed.

Do you think if i move to London ( obv get a new IP ) - that cPanel will crash and burn, more specificly, all the domains on it, since they all have DNS settings pointing to the current IP.

Please note, im not talking about the A/Nameserver records of the domains where i registered them, im talking about within the DNS settings of WHM - all the subdomains and stuff have A records pointing to the current IP address.

Do you think, if i move to London & change my cPanel lisence IP to new IP, that WHM will pick this up automatically or will i need to do some crazy stuff to hax it all back together?

Please advise :)
