We plan to migrate from SBS 2008 (Exchange 2007) to Exchange Online
We will deploy a new VM (2012 R2) for the DirSync installation
After the Exchange Online MIgration is completed. We plan to install a new windows 2012 R2 Domain Controller and move all the shared folder and stuff left on the SBS Server and after decommission the SBS Server.
In between the Exchange Online migration and the Decommission the SBS Server we will have couples of week in between (holidays)
My two questions :
When I will deploy the DirSync do I need to upgrade the Forest / Domain Level to a level higher then the SBS 2008 will support ?
After the Exchange migration is done and I turn off all the services of Exchange 2007. Does SBS will "panic" if the Exchange Server is Off, All the services disabled ? ** Sometimes SBS doesn't react as a normal infrastructure. **
If anyone had done this type of migration please share.
