Migration FSR TO DFSR Problem

Question

Hello,

I have a Windows Server 2008 R2 server with Active Directory installed, and I want to migrate it to a Windows Server 2022 server. The domain and functional levels are 2008 R2. However, due to FSR technology, I couldn't proceed with the migration.

To proceed, I tried running the command dfsrmig /setglobalstate 1 as an administrator in the CMD window on the Primary DC server, but I encountered an error:

"Error: 87. Please check the DfsrMig log files under the windows\debug directory."

When I checked the error log file, I found the following errors:

[Error:87(0x57) Config::AdWriter::CreateSysVolMigrationGlobalObjects adwriterserver.cpp:1749 2032 W The parameter is incorrect.]

[Error:87(0x57) Config::AdWriter::CreateSysVolGlobalObjects adwriterserver.cpp:336 2032 W The parameter is incorrect.]

[Error:87(0x57) Config::AdObjectEditor::AddObject ad.cpp:2859 2032 W The parameter is incorrect.]

[Error:16(0x10) Config::AdObjectEditor::AddObject ad.cpp:2859 2032 U No Such Attribute]

But I cannot proceed further. I am performing these operations using the Administrator account, which has Enterprise and Schema Master privileges.

How can I resolve this issue? I am unable to migrate the Domain Controller due to this problem.

Hi @RamazanSar-4303

May you should run adprep /forest manually to restore or repair some objects.

I invite you to read this article I think it talking about the same issue: Unable to migrate from FRS to DFS on Native Windows Server 2012 R2 Domain

We are getting the same errors, yes. I did not fully understand how to downgrade the schema version. How can I do this?
