Cutover is relatively easy, requires minimal setup, doesnt make any irreversible changes to the on-prem mailboxes and will probably migrate all objects you care about. Start with the Technet documentation here, it covers most details: <a href="https://technet.microsoft.com/en-us/library/jj874016(v=exchg.150).aspx" rel="ugc">https://technet.microsoft.com/en-us/library/jj874016(v=exchg.150).aspx</a>&nbsp;<br />

You will need a valid 3rd party certificate though, you can get one for free from sites like StartSSL or Comodo.

Thanks Vasil<br />

We already have an SSL certificate as we run a mail server on SBS 2011, users us RPC over HTTP etc. <br />
<br />
Is this the same certificate? <br />
<br />
I'll take a look at the link<br />
<br />
Many thanks

Yes, you need the cert for RPC over HTTP, so you should be set.

We generally use Bittitan MigrationWiz for such migration.<br />
<br />
Have a look, it is worth it.<br />

Hi Experts<br />
<br />
We run SBS 2011 and have 31 active mailboxes, we want to move to Office 365.<br />
<br />
How do we start? What are our options? I understand we can do a cutover migration or a stage migration? <br />
<br />
Any advice (considering we're a small company) would be good!<br />
<br />
Many thanks

Migrating 31 users to Office 365

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Microsoft 365

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
