When migrating to another set of nameservers, there can often be downtime incurred. In this guide we will walk you through adding your domain to ZEIT and setting it up before migrating the nameservers, ensuring no downtime at any point.
To get the process started, you will need to add your domain to your account or team by using the following command:
This command will add the domain to your account and output some information that you will need to verify the domain is yours.
You will receive two options:
Adding a domain with Now CLI.
To avoid pointing the nameservers to Now prematurely, use the TXT method for verification.
With your domain provider, create the TXT record using the
name (also known as
_now and the value provided when adding the domain.
Note: If you have lost the value before verifying the domain, you can use
now domains inspect <domain> to retrieve the verification methods and value again.
Now will check in a loop for whether the TXT record (or nameservers in another case) has been added and then mark the domain as verified when it detects them. You can force Now to check for the verification by using the following command:
Verifying a domain with Now CLI.
Now that your domain is verified you have more control over it with Now. You can now generate an SSL Certificate, add any DNS Records, and deploy and alias your application, all ready for when you switch fully over.
You can generate a certificate for your domain from either the Web UI or Now CLI.
With Now CLI, you can generate an SSL certificate for your domain and all subdomains, called common names (CNs), with the following command:
You will then be asked to solve a DNS challenge, required for the Certificate Authority (CA) to prove that Now has sufficient permissions, consisting of two TXT records.
Once these TXT records are added to your domain via your domain provider, run the
now certs issue command again as above to attempt the certificate issuance again.
From your certs dashboard, from either your account or team, you can issue a new certificate by clicking the "Issue" button from the top-right corner.
A modal will open and you can add two values, both
*.<your domain> and
<your domain>. Hitting enter after each value is in the input. When done, click "Issue".
If you haven't previously solved the certs DNS challenge, a new modal will show asking you to add two TXT DNS records via your domain provider.
Once the DNS challenge is solved, you can proceed to issue your cert from the same modal, which will then verify the challenges and proceed with the cert issuance if they are met.
The next step is to add any DNS records your domain might have had before. For example, MX records.
In this example, I'll take Gmail's current MX records and add them with Now CLI:
The above demonstrates using the
now dns add command to add multiple MX records, of which are currently Googles', to your domain.
If you are not yet acquainted with deploying with Now, we suggest you follow the Deployment Basics guide first. It continues great information for how you can get up and running with Now.
In short, to deploy your app with Now, you can use the following command, after some configuration if necessary:
After Now finishes deploying your app, you can then alias it by using
Now your domain will be pointing to the deployment you passed it, and ready to move your nameservers across to show that deployment.
Once your domain is set up properly and contains all you need for a successful migration, you will be free to change the nameservers of your domain to point to ZEIT DNS via your domain provider.
now domains inspect <domain>, you can find your intended set of nameservers to use with your domain, in case you have forgotten them when you first added the domain.
Once the nameservers have been added and propagation is complete, your domain will successfully point to your aliased deployment from your domain, which is including a free SSL certificate and any DNS records you setup!
