The Great Migration

Microsoft Office 365 offers a compelling business case to organizations - trade resource intensive on-premises infrastructure and software for services managed by Microsoft and delivered from the cloud. The rate of adoption tells us the benefits are attractive. In fact, recent Mimecast research finds that 99% of Office 365 users are receiving some benefit from the service.*

The research also uncovered some very interesting information regarding how businesses with between 250 and 7,500 email users are making the move to the cloud with Office 365. First the survey found that 58% of companies were using Exchange Online with another 29% planning to in the next twelve months. For those thinking about how many employees to move up to the cloud, our research finds that the average is about 70% of the total email users. I believe this shows the importance of hybrid environments, an area that Office 365 has proved it’s supremacy over other cloud collaboration solutions.

Given that for most organizations, not everyone will be on Office 365, our research set out to find the other mail servers being used. Not surprising, many flavors of Exchange on-prem were in use with the following breakdown.

 How are orgs getting to the cloud?

With a large number of organizations already moving to the cloud and many others considering Office 365, it’s interesting to look at how companies are making the transition. Mimecast research finds that about one third of companies are using a cutover migration while two thirds are opting for a hybrid migration. Hybrid migrations are generally less risky as users can be switched over a longer time period with a safe fallback position to on-premises if something should go wrong. Organizations making the move are also keenly aware of the need to port archived email to the cloud. 9 in 10 organizations have already or plan to move existing mail to the cloud.

 

Migration Concerns

In addition to what migration approaches most companies are using, Mimecast wanted to find out what were the top concerns when making the move from on-premises email. I guess not surprisingly, 6 in 10 were most concerned about downtime during the migration. Especially considering that over 85% view email as critical to their organization. One surprising stat was that in the event of an Office 365 disruption, almost half of the organizations said they would just wait for Microsoft to restore the service while the other 50% would look to a third party for help with email continuity. It’s obvious which employees would be more productive!

Other top concerns for the migration include security concerns of senior employee’s email privacy, on-premises system requirements for sending email and the overall impact to employee productivity.
