We have AD forest functional and domain functional level of 2003. We have 1 2003 DC and multiple 2012 R2 DCs. We're looking at implementing DCs in Azure, preferably using Windows 2016.
Are there any issues with using a 2016 DC in Azure whilst we have 2003 & 2012 on premise? We'll be moving the domain and forest functional levels to 2012 later this year.
Our plan at the moment is to:
- Update the AD sites and services with Azure sites and subnets. Create site links as needed.
- Deploy new VMs in Azure with a separate non caching disk for SYSVOL and DC logs
- Install AD on the Azure VMs
Azure Domain Services isn't suitable for our scenario.
Thanks
