    Office 365 cloud email. Can you explain the DNS for it please? Migrating data...

    Hi,

    Just started working on migrating our email system from a local exchange server to office 365 and want to get my head round it all including DNS and downtime when migrating accounts and data.

    So you sign up for office 365 for education, add your domain. Your domain would be the same as your website address without EduGeek.net - The I.T. Professionals' life line. Right?

    Our LEA provides us with a external IP for our local server containing our website which we pass to fasthosts although I've never had to alter this.

    Office 365 requires a mx record for exchange mail. This would get added into the fasthosts DNS system that currently has the http schools website on. Or even altered as im guessing there is already one there for the current system, need to check that.

    After changing the DNS record the emails would then get sent to the cloud exchange server.

    So this would mean that the email system would have to be taken down for a few days whilst the email accounts with the data is transferred and the DNS is altered.

    How would you minimise this downtime? can you create accounts and then transfer the data whilst they are using the new system? My plan next is to try and find the tools for transferring from a local exchange to the cloud exchange server.

    Any info you can give will be greatly appreciated.

    Moving to Cloud Services forum (Yes, I know it can go in either, but as a product related topic it can live there).

    All depends on your Exchange server and how you want to do it. Can you confirm what Exchange you are running and if you have SSL. And Autodiscover setup on it?

    But basically at no point does the email system have to be offline. At the end of the day the data is either local or cloud. So configure all the accounts in Office 365, send out account details, change MX record and then migrate all emails.

    Depending on the Method of migration you may have a period when Office 365 is working but not all old mail has transferred yet. However it is usually very quick to do so.

    I do lots of Office 365 migrations and each one is different due to the current school setup so until you explain what you have it's hard to help any further.

    HTH

    The MX records in DNS control where your email is sent to. For now you want to add the text records required to validate your domain etc, you can then set up Office 365, start the migration process and once the bulk of your email has copied over change the MX record to Office 365 and do a final sync.

    That's very brief, but a quick over view of the process.

    Thanks both,

    Don't have access to the current system until late April so can find out details then. Have a better understanding of the DNS and what steps are needed. May get back to you with further details later if that's ok.
