Migration of Active Directory DC 2008 to 2019 (FRS to DFSR & Move FSMO Roles & Demote old DC)

In this tutorial I covered the direct migration of Windows Server 2008 DC to Windows Server 2019 DC with full clear steps and they are classified in 3 main steps:
1.FRS to DFSR :
1.DFL* & FFL* to minimum 2008
2.Check healthy DCs and synchronization
3.Start Migration of FRS to DFSR in Quick Mode
Quick mode has 3 phases:
1.Dfsrmig /setglobalstate 1
2.Dfsrmig /setglobalstate 2
3.Dfsrmig /setglobalstate 3
Each phase takes time according to the number of DCs and network bandwidth between them and to check the status of every phase, you use this command : Dfsrmig /getmigrationstate.
You can find more explanation on checking AD and Migration phase in a word document this link:
mega.nz/file/N...
2. Move FSMO Roles:
1. Promote 2019 DC
2. Start Moving Roles using GUI as in the video, and to enable schema master Snap-in Role:
1.run this command using CMD as administrator
regsvr32 schmmgmt.dll
2.start - run then type mmc.exe then enter
3.add snap-in (schema)
4.Choose Domain Controller and Move the Role to.
You can find detailed steps in the below link:
mega.nz/file/J...
3. Run netdom query fsmo to check that all roles have moved to the Wanted DC.
3.Demote Old DCs and if you want raise DFL* and or FFL* to (2012/2012R2/2016)
*DFL: Domain Functional Level
*FFL: Forest Functional Level

Hello, excelente video, but... In the case of having 2 file servers with Windows Server version 2008r2, is there any problem if I want to migrate 2 domain controllers from w2k12 r2 with FRS to DFRS??? I lose some sharing compatibility???

[@AL-Techs]

first. you do not migrate 2 servers , you apply the commands on the PDC i prefer. and all the servers will be migrated from FRS to DFSR. but the point here ia that after migration you need to ensure you have no errors in replication. since if you are using DFS on file server it depends on the healthy replication between DCs to be successful. Hope I answered your question.

good one

[@elangoramalingam667]

The Functional level could not be raised, The error is. The FSMO Rules ownership could not be verified because its directory partition has not replicated successfully with last one replication partner, because of this can not raised to windows 2008 from windows 2003, please help for this

[@AL-Techs]

sorry for the late reply.. Did you demote any DCs lately??
