You want to change your email from your current hosting provider to Google Apps. What should you do to ensure the change does not take more than an hour?
- Change the MX record to the ones provided by Google
- Change your NS records to Google IP address
- Create a new A record
- Check and lower the TTL
EXPLANATION
It's always a very good idea to check and lower the Time-To-Live (TTL) for a domain to ensure that any changes made are propagated in a short time frame and your customers and boss remain happy. NOTE: TTL is normally specified in seconds, you need to divide by 60 to get minutes.https://mediatemple.net/community/products/dv/204644120/understanding-ttl-(time-to-live)
In the end you will need to change the MX record, but changing the MX record does not change how quickly the change will happen.
