Azure ad connect install error

Question

Hi guy's

We having an issue with upgrading/migrate our current Azure ad connect version 1.4.18 from a server 2012 R2 to last version of Azure-ad connect on a server 2019.
What we did was export the configuration of the current AD connect server with MigrateSettings.ps1 to a json file and use this json file on the server 2019 to install the Azure-ad connect and select both options staging mode and start the sync after configuration is done but configuration at the last moment come up with this error. I have no idea what is means
I check the current domain and forest fuctional level is at server 2008 R2

*[ERROR] System.Exception: Failed to set the connector. *

Any suggestion?

UPDATE:

Just removed the AD connect on the new server and ran it again and get the same error, and in the log see this:

[13:23:51.320] [ 4] [ERROR] ExecuteADSyncConfiguration: configuration failed. Skipping export of synchronization policy. resultStatus=Failed

Hi @James Hamil Thank you for your reply, I have upload the picture one more time as attachment.

Hi @James Hamil I wonder if you had the time to look at the error message?
Thanks

Answer 3

Hi @Shahin Mortazave , have you tried changing the source anchor? This user had success with changing from mS-DS-ConsistencyGuid to the mail attribute.

If this doesn't work I'll most likely need to open a support ticket for you so we can look into your environment. Please let me know.

Best,
James

Hi @James Hamil thanks for your reply,
where can I check what is the source anchor? we simply export the configration from the old server and try to importing it to the new server!

Thanks
