Integrating a secondary website into a primary website - how to change website across ZOHO One - CRM/Campaigns/SalesIQ

Hello,
We will soon merge two websites into a single website for improved SEO. The website associated with SalesIQ and Campaigns will be eliminated in favour of our primarly website. 
Please advise what might be effected and steps to facilitate this change.
Thanks in advance.
