I am in process of migrating from and old installation of AAD-Connect (1.4.18.0) to a new server running (1.5.45.0)
I'm not super clear on the migration process, I've installed AAD Connect on the new server in staging mode matching the install properties as best I know.
I then ran this tool https://github.com/Microsoft/AADConnectConfigDocumenter and compared the report output. I am not certain that I understand the report, from the name of the report it implies that is has applied config from new server to old server which seems backwards. There are also a million red lines in the output. It seems to have a function to create a 'fix differences' script, but this doesn't seem to contain many instructions so I am not clear on what its doing.
Are there manual steps I need to do before running the 'SyncRuleChanges.ps1' script to update the new server? (if so, how) I don't want it to make it EXACTLY like the source server and then cause the new one to leave staging mode before I am ready.
My new server does not currently have sync enabled, but I read then that it should (with staging mode also enabled) is this right?
Alternatively, this article: https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-import-export-config
says there is a script in the tools folder of the new installation (MigrateSettings.ps1) that can export the config from the old box and be imported on the new. This method seems easier, does this copy everything I need? is there a preference which method to use?
thanks
