Help With changing hosts for a domain.

I was recently assigned a project to migrate our landing pages from Marketo(a marketing automation tool which gives you the option of creating landing pages based on a domain chosen by you) to our wordpress server. Currently the networking and web devs have decided to clone all our landing pages on the new server and then map the DNS( www.example.com) from the old to the new server. This would mean I just have to create all the landing pages and its assets we currently use in Marketo on the wordpress server and make sure the hierarchy of the files is the same So For example, example.com/data-cleansing clone would be IPAddress/data-cleansing. When we map example.com to the new server, it would change from IPAddress/data-cleansing to example.com/data-cleansing similar to the URL of Marketo landing page. We would have no down time, and if we are using the link example.com/data-cleansing somewhere, access to it won't be affected. My question is: is it this simple or is there sth more to it?
My research shows that if both the web servers are static, this method would work conditional on the fact the both the servers are using the same CMS. How do I know whether the servers used by Marketo are static or dynamic? Secondly, our server is using wordpress and I am not sure what CMS Marketo is using. Does these things matter or not?
