I need to upgrade our Domain and our current domain name is not our corporate domain name due to legacy situation at time of creation and long before I was here. The plan is to create a new 2019 domain, create a full trust and migrate to it using the corporate domain name.
I have read up on making the migration using ADMT, but I want to make sure there isn't anything that could pose a problem I'm not aware of since our current domain is in hybrid state using the the corporate domain as our email domain. So while our current AD domain name is asdf.com our email domain name is corpname.com and is a hybrid Exchange 2010 / Office 365 configuration.
For one thing, currently we cannot user our UPN to log into our domain since it is different than our public /email domain name. When I migrate to the new Domain I am hoping I can seamlessly begin having them log in with there UPN.
I am hoping I can do the following:
Create new corp domain
Create Full Trust
Migrate Users to new Domain
Migrate User Computer accounts to new Domain
Migrate Servers to new Domain
Configure LDAP Authenticating devices to new Domain.
Break Full Trust
Disable Hybrid Exchange environment.
Decommission old Domain
