While I provide many versions of Azure AD Connect Sync on this blog, it's important to note that Azure AD Connect Sync v1 has been out of support since August 31, 2022. It is crucial to begin planning and implementing this migration now to avoid any future issues.

What does this mean?

Azure AD Connect Sync is the tool that allows local identities to be synchronized to Azure AD, and to a lesser extent, permits reverse synchronization of some attributes. The version 1 of this tool (Azure AD Connect v1) is in the decommissioning phase. This means that Microsoft will stop supporting this version, which could affect identity synchronization and resource access.

What should I do?

It is imperative to migrate to cloud sync or Azure AD Connect Sync v2 immediately. These solutions are successors to Azure AD Connect v1 and offer similar features but with updates and enhancements. The migration process to these new solutions may require careful planning and implementation, especially if you have a large infrastructure with many identities to manage.

Why is this important?

The end of support for Azure AD Connect V1 is a significant milestone. This means that if you continue to use this version after October 1, 2023, you may encounter major identity synchronization issues. Moreover, no security or feature updates have been made for several months.

Migration to a new version is no longer an option; it's a necessity. It's essential to begin planning and implementing this migration now to prevent any future issues.
