Recommended Steps:
In short, the recommended steps to manually do the syncronization is:
- (Full/Delta) Import from on-premises directories, such as Active Directory
- (Full/Delta) Import from Azure AD
- (Full/Delta) Synchronization from on-premises directories, such as Active Directory
- (Full/Delta) Synchronization from Azure AD
- Export to Azure AD
- Export to on-premises directories, such as Active Directory
Understanding the steps
The keys to understand the steps:
- Import (step 1,2) imports things from AAD or on-premise AD to the AAD Connect server for comparing purpose.
- Synchronize (step 3,4) doesn’t really make things change. Imagine it as comparing the things that just imported, and find the differences – it doesn’t change anything!
- Export (step 5,6) does make things change.
Behind the syncronization
If you are also interested in the “Run Statistics”, e.g. “Connectors with Flow Updates”, read the reference [2] below. This document is from an old product FIM 2010, which is renamed as MIM 2016 by now.
Are we talking about “AAD Connect”? Well… I didn’t find a document of AAD Connect about the statistics by now, if you find it, let me know. For now, read the reference [2] and just for reference.
