Conflicting entries in dfsr schema preventing migration from frs to dfsr
Hello,
I’m experiencing a very similar issue and I’d like to know if the person who posted this managed to resolve it—and if so, how they resolved it—because I still haven’t found a solution. In my environment, I have 3 Domain Controllers: two running Server 2008 R2 and one running Server 2012 R2. The schema version is 88, but I cannot migrate from FRS to DFSR. When I run the command, I get the error: "Error: 87 Incorrect".
I also checked the log file located in C:\Windows\Debug and I'm seeing an error similar to the one shown in the screenshot I’ve attached.
I have not figured out a resolution. Do you also have cnf entries in the schema in adsi edit. The schema version in use in this domain is also a schema version 88 which corresponds to server 2019 version. I had managed to remediate the schema conflicting entries but still had the same results. Being that you are having the same issue I am beginning to wonder if once the schema is past a 2016 version if it makes changes to dfsr that prevents the migration. If you go into dfsr management and try to view replication groups or create a replication group do you also get a error about the schema not being extended or extended incorrectly?
