Hi,

I need advise to migrate from On Premise Exchange 2007 to Office 365.

I need more information about the Directory Sync. We want to do a cut over migration from our On Premise Exchange.

The reason for the Cutover the Exchange and the Active Directory domain is currently install on a hosted Virtual Solution and we want to get rid of it.

The migration steps
Install the Directory Sync on the On Premises.
Import all the users / mailboxes on Office 365 with the Directory Sync /  Staged Exchange
Activate the licenses for Office 365
Install all the users Office 365 on their PC
Move the DNS
Deactivate the Directory Sync.
Uninstall Exchange 2007 from On Premises.

My Main question his what will happen to Office 365 after we deactivate the Directory Sync ?

Does all the accounts and info will be managed over the 365 Portal or I can run into issue because we import it ?

Does anyone have done any of these type of migration and might share any pitfall or issues ?

Thanks

Hello,

Dirsync works only one way - from on premise to the cloud.

Uninstalling dirsync doesn't mean anything else than cutting the connection to your on-premise AD, therefore you will not be able to add user or do any AD-specific task.

You will do them from the cloud starting Dirsync uninstall point.

After the DirSync in uninstalled the Office 365 will run independant, and I will be able to proceed with the uninstall of the Active Directory and Exchange 2007 from my on premise install ?

Yep, basically it only means that no AD change will propagate to the cloud, therefore Office 365 will no longer pe impacted in any way.
