Configuring MX record switch over to hosted Exchange

The idea of what we want to do is have our Exchange server be the primary host of our mail. We also want to keep InMotion as a backup host in case our server goes down.

So would we have to do the following..

1. In MX Entry in CPanel, change the radio button to Backup Exchange.
2. Add the Exchange server MX record and give it a priortiy of 0
3. Change the Inmotion MX record to a priority of 10

4. Go into DNS Manager in our Domain Controller and change our MX record to priority of 0.
5. Add the InMotion MX record and make that a priority of 10.

We also have a firewall that we store our pointer records on. Do we have to add MX on there too?

I'm also assuming that I should do this on a Friday night and that it could take up to 48 hours to complete?

Hello Smetts,

The Local and Remote options are one way or the other and setting our server as a backup will not work. I strongly suggest setting the option to either automatic or backup.

Hello Smetts,

It is best to keep it at automatically detect settings. As for the priority on the other server you should be fine. As long as on our system your exchange server is a lower number than ours, your emails should go to the correct place.

Hello Smetts, You should only have to change the MX Entry as you stated in steps 2 and 3. You should not have to modify DNS unless you wanted exchange.yourdomain.com to point to your exchange server. Regarding the firewall you may or may not have to modify the rules/entries as I am not sure what type of system you are using for it. Best Regards, TJ Edens
