7 tips when going from Exchange to Office 365:

1. Where do I start? Call us --we're happy to hop on a discovery call to see if this is a fit for you!

2. Transitioning is always a Transition
A two-step migration involves migrating to a newer Exchange Server version prior to migrating to Office 365. For instance, an organization might migrate from Exchange Server 2003 to Exchange Server 2010. This is usually the preferred method because older versions of Exchange Server can pose significant migration challenges...but it's nothing Grumman can't handle!

3. Organized & Ready to Migrate?
We help you in prep time for the migration project and have no surprises. We have done this many times and have worked out a majority of the hiccups with our clients. No need to have long-drawn-out training, we also give you self-help tools from Microsoft such as Office 365 Health, Readiness and Connectivity Checks tool. Plus, we test before during and after to make sure all engines are humming smoothly and every car (user) is driving well on their road to access.

4. Remembering the Clients
While preparing for an Office 365 migration, we at Grumman verify client readiness. Users will have continual access to their mailboxes through Outlook Web App & we always inspect and test their browser compatibility.

5. Migration Meet & Greet
There's no rule that says you have to perform a staged migration quickly and then immediately deprovision your local Exchange Server environment. To the contrary. You can maintain coexistence between your local Exchange Server environment and Office 365 Exchange for as long as you want. Even permanent coexistence is acceptable.

Of course, functionality isn't the only consideration. If you are under the gun to complete the migration and deprovisioning as quickly as possible. The reasoning behind this pressure is hybrid Exchange Server environments involve two complete Exchange Server organizations (the local Exchange organization and the Office 365 Exchange organization).

Grumman has you covered! Every hybrid Exchange Server deployment that's been undergone has been well tested by Microsoft and are fully supported. And we are the best at adhering to Microsoft best practices.

6. What happens after migration? Things like break free/busy calendar sharing or the concern for lost emails, archiving, etc;

If there is a hybrid deployment consisting of on-site servers and Office 365, . In this type of situation, free/busy lookups will fail for any mailbox already migrated to Office 365, and Exchange has the free/busy sharing relationship established but Office 365 does not, Microsoft already has a workaround for this problem. Grumman has their secret sauce for it all!

7. Use the Right Tools for the Job
You should also take advantage of the available tools to make the migration process easier. Microsoft provides some decent tools for migrating Exchange Server mailboxes to Office 365. I already mentioned the Office 365 Health, Readiness and Connectivity Checks tool, but there are others.
