Best practice to link main website page to BETA website

I will explain briefly.

I am working for a new booking accommodation platform. They currently have two different websites:

• the main website [landing page] with all the info about the business

• the BETA platform [with the listings, profile dashboard and search bar]

For the moment if you are on the BETA and then click on the company logo on the nav bar you go back to the main landing page.

To go back to the BETA when you're on the Landing there is a link on its respective nav bar and also all over the site.

NOTE: the BETA platform and the Landing page have different and separate nav bars and links [the design is similar] - The BETA has a profile dropdown menu that cannot be replicated in the main landing page since the websites have been done using two different services.

→ Now the company needs to have a proper homepage for the BETA platform with also some new features, but it also still needs to keep the main landing page.

Which you think is the best practice to link the two homepages without confusing the users?
