My apologies if this isn't the correct forum. My question cuts across multiple technologies. My company has just taken on a new customer that has the following setup.
- Windows 2003 domain that is a mix of Windows 2003 and 2012 DCs.
- Single label domain (SLD) for AD DNS.
- Exchange 2003 is the production mail platform but someone had installed Exchange 2010 and the schema has been extended. Nothing has been migrated to the Exchange 2010 platform.
Customer's objectives (in no particular order)
- Migrate from on premise Exchange to Office 365.
- Migrate from SLD to a FQDN.
My questions.
- Can I migrate to Office 365 with a SLD? I found one reference in a MS article entitled "Single-Label-Domains in Active Directory Domain Services (AD DS)Considerations, Migration, and Co-existence" that seems to indicate that it isn't supported. I haven't been able to find any supporting information.
- I know that renaming a domain with Exchange 2010 in it is unsupported, but if Exchange 2010 is uninstalled/removed, does this put the domain back into a state that a domain rename is supported?
- If domain rename isn't possible, can ADMT be used to migrate to a new domain, considering that Exchange is in the environment?
