How do I migrate SBS 2011 AD to WIndows Server 201`9?
I am in the process of removing the SBS 2011 server. I have the new 2019 server attached to the domain. I have added the roles for AD. I get an error saying the old server is not at 2008 or higher. I then raised the domain functional level to 2008 R2. Verfied in ADUCT, Domains and trusts too. I still get the error when trying to promote the AD on the 2019 server. Thanks in advace.

Can you help me out to also make sure all the FISMO roles are moved properly as well? TIA
# ADDS FSMO Roles
Get-ADForest | Format-Table SchemaMaster,DomainNamingMaster
Get-ADDomain | Format-Table PDCEmulator,RIDMaster,InfrastructureMaster
# Destination DC for Operations
$DestinationDC = "NewDC100"
# Transfer FSMO Roles
Move-ADDirectoryServerOperationMasterRole -Identity $DestinationDC -OperationMasterRole 0,1,2,3,4 -confirm:$false

But as Philip suggested, you probably forgot to upgrade FRS to DFSR.
