Upgrading the Mimecast Synchronization Engine
When upgrading an Mimecast Synchronization Engine version, the following must be considered:
- If you're upgrading a Mimecast Synchronization Engine version 3.0.x or later, the new version can be installed over the top of your current installation. You don't need to uninstall the older 3.0.x version first. Follow the instructions in the "Installing the Mimecast Synchronization Engine" section above.
