Namecheap Wordpress migration

[ed79]

I have a Wordpress site on Namecheap shared hosting. It's all running fine and I'm not looking to change; however:-

I own 2 domain names - that's say dom1.com and dom2.com. My hosting account was created for dom1.com but is no longer hosting anything. When I later bought dom2.com I installed WP as an add-on domain under dom1 hosting account.

Now, dom1 is about to expire and I don't want/need to renew it. I've been on to Namecheap support asking about making dom2 the main domain and the part that worries me is:-

The files of an old domain will be re-assigned to the new domain. This means the new main domain will be pointed to the /public_html folder that may contain your old files of the previous main domain. Some configuration changes will be needed to your website once the domain name is changed.

The URL references in the database will not be reassigned to a new domain, and this will most likely corrupt the working website and highly developed CMS. The appropriate database changes should be made in this case.

I'm not reassured by supports answer to this so and I don't know what is going on inside Wordpress that may be broken. Can anyone help with what changes would be needed to Wordpress if dom2.com is made the hosting domain?

If you've made it this far - many thanks!

Thanks guys. It's a fairly small site so not too much to check through, but it is making me a bit of money in amazon commissions so I think it's best for me to wait until after black friday etc before messing around with anything.
