switch main domain and parked domain in account

One solution would be to:
1. Remove domainB.com as a parked domain
2. Go to WHM, modify this cPanel account
3. In the domain field, change domainA.com to domainB.com
4. Click "Save" and wait for the process to complete
5. Add domainA.com as a parked domain

 

I wanted to give you some real world experience, when I did this exact same thing: Switch a Parked Domain (DomainB.com) with the main domain (DomainA.com):

The customer had email accounts with both DomainA.com and DomainB.com, and also had some email forwarders for only DomainA.com.

Here are the steps I took, and what resulted:

1) In cPanel, I documented the email accounts and forwarders (simple copy and paste to a text file)

2) In cPanel, I clicked on Parked Domains and removed DomainB.com from being a parked domain.

3) In WHM, I modified the account by changing the domain from DomainA.com to DomainB.com.

4) In cPanel, I noticed that all of the email accounts (both for DomainA.com and DomainB.com) are still intact. However, all of the email forwarders were changed to DomainB.com!

5) In CPanel, I went into Add-on Domains and added DomainA.com as an Add-on domain (we decided we wanted it to be an Add-on and not Parked, so that we can track statistics of the usage of DomainA.com -- when you Park, you do not get separate stats)

6) In cPanel, I went into Redirects, and redirected DomainA.com to DomainB.com, "with and without www" and "wildcard" both enabled. Now, if you go to DomainA.com, it redirects to http://www.DomainB.com/somepage.htm. Perfect!

7) In cPanel, I had to delete the existing forwarders, since they were now for the wrong domain (DomainB.com), and then recreate them with the correct domain (DomainA.com). Thankfully, all email boxes are all OK!

So, that is my experience, your mileage may vary. I hope this helps.

Thank you Scott. I found your summary very helpful in guiding my own testing. My experience in ver 11.25 was the same as yours.
