IdentityMapLog csv generated by TfsMigrator doesnot show all identities

Question

I'm trying to migrate TFS (2017.3) to VSTS. While following the migration guide, I am at a spot where I can't move forward. My IdentityMapLog.csv generated after Prepare command only shows 3 identities however my TFS has 4000+ identities as seen from tfsconfig identities command (which shows True for Match and Exists both).

Any ideas?

Thanks

Seems the AD was not synced. Please make sure you meet the Migration Prerequisite:

1. Azure Active Directory: AAD is synchronized with on-premise Active Directory environment.
2. Compliance (if applicable)

Please exactly follow the guide document to do the migration: TFS-to-VSTS-Migration_WhitePaper.docx

Azure Active Directory

User authentication in Team Foundation Server is handled on-premise by using Active Directory. With Visual Studio VSTS, users are authenticated through an Azure Active Directory tenant which works very similarly to Active Directory on-premise.

Synchronizing identities and groups with Azure AD Connect

By synchronizing your on-premise Active Directory with Azure Active Directory, your team members will be able to use the same credentials to authenticate and your VSTS administrators will be able to leverage your Active Directory groups for setting permissions within your VSTS account. To setup the synchronization, you will want to use the Azure AD Connect technology. The documentation for setting up Azure AD Connect is available at https://aka.ms/AzureADConnect.

Identity Map

The identity map is one of the most important configuration files for the TFS Database Import service since it is what maps the on-premise Active Directory identities with a matching Azure Active Directory identity. This is so that each of your team members will automatically have their personal settings, security permissions, and history tied to their Azure Active Directory user account which makes for a positive experience working in Visual Studio VSTS on the first day.
