This is an example how I upgraded Dirsync to AADConnect, and how to move an old installation to a new server.
You can download AADConnect here :
https://www.microsoft.com/en-us/download/details.aspx?id=47594
Upgrade the server
Start AADConnect
Wait until the configuration is analyzed
Click Next
Use the Office 365 credentials of the administrator used in dirsync
This account must be an Enterprise Admin !
Click Upgrade
Wait until the upgrade is finshed !
After the upgrade click Exit
Export the configuration
Select File => Export
Click OK
Select the export folder and Click OK
When the export is finished, click OK copy the export folder to the new server.
Import the configuration on the new server
There are no connectors available
Click File => Import
Click OK
Select the folder where the exported configuration is saved
Fill in the AD admin credentials
Wait a few seconds
Fill in the Office 365 admin credentials
Click OK
Click OK
After installation reboot the server!
After the reboot, execute a full sync in powershell (See below)
Disable AADConnect on the old server
Disable the Microsoft Azure AD Sync service.
It is now safe to remove AADConnect or to decommission the old server.
Force an update
Full update
Start Azure powershell;
cd “C:\Program Files\Microsoft Azure AD Sync\Bin”
.\DirectorySyncClientCmd.exe initial
Delta update
Start Azure powershell;
