Install wp @ ip address to migrate to domain later

Hello, I have a client whereby we are doing a site redesign and transferring content from Joomla to Wordpress. We are unable to utilize the domain until the last moment, so I did a fresh single wp install @ a dedicated ip address on our VPS. Everything went fine, but I realized afterwards there me be a potential issue when we go to propigate to domain name. (eg, database, permalinks...)

Anyone have any experience with this? And if so advice on how-to manage effectively?
Thanks in advance,
Lance
