Migrating Sophos central email gateway from internal exchange to O365

Question

Hello, 
 
 we are migrating from internal exchange to office 365 and we already use Sophos central email gateway to filter mail to our internal exchange server so this should be a pretty straightforward switch but I want to make sure we don't miss anything. based on what I reading all we would need to do is change the internal destination to point to ourdomain.mail.protection.outlook.com to get mail flowing since everything else is already done from our initial setup outside bypassing the EOP for office 365, restricting delivery IP's and configuring the secure connector correct? I see there is a Connect link beside every one of our domains under O365 connection do we need to do that as well? 
 
 thanks in advance.

Hello there, 
 Thank you for contacting the Sophos Community. 
 I would recommend you to reach out to our Help Desk service to assist with this implementation/migration. 
 You would also need to change your MX records to Point only to Central and add all the Mailboxes that would be receiving email. 
 Regards,

Hello, 
 Yes, you are correct it is to setup Auto search and Destroy. 
 
 Connect your tenant domain to allow Office 365 Security to run. 
 Disconnect your tenant domain. 
 Click Configure O365 Security to turn on Auto search and destroy for your Microsoft Office 365 users. 
 
 Regards,
