Sync is not interrupted and does not impose a risk to productionįor permissions information, see the permissions required for an upgrade.Īfter you've enabled your new Azure AD Connect server to start synchronizing changes to Azure AD, you must not roll back to using DirSync or Azure AD Sync. Supports Windows OS (Operating Systems) upgrade. Safest approach and smoother transition to a newer version. With two servers, you can prepare one of the servers with the new release or configuration and change the active server when you are ready If there is an issue while in-place upgrading, you cannot roll-back, and sync will be interrupted If you have a single server, you can upgrade the installation in-place on the same server This is the easiest method for customers with an express installationĪuto-upgrade version might not include the latest features There are a few different strategies that you can use to upgrade Azure AD Connect. Customers who have not upgraded in 12-18 months (about 1 and a half years) should consider a swing upgrade instead as this is the most conservative and least risky option. Servers that have been in production for several years typically have had several patches applied to them and not all of these can be accounted for. In practice, customers on old versions may encounter problems not directly related to Azure AD Connect. If you want to upgrade from DirSync, see Upgrade from Azure AD sync tool (DirSync) or the Swing migration section.

In-place upgrades of DirSync or ADSync are not supported, and a swing migration is required. It is currently supported to upgrade from any version of Azure AD Connect to the current version. To see what the latest version is, and to learn what changes have been made between versions, please refer to the release version historyĪny versions older than Azure AD Connect 2.x are currently deprecated, see Introduction to Azure AD Connect V2.0 for more information. We are constantly making upgrades to AADConnect, and these upgrades include fixes to security issues and bugs, as well as serviceability, performance, and scalability improvements. It's important that you keep your servers current with the latest releases of Azure AD Connect.
