Upgrade the Transaction Engine

Add the account of the target device to the Active Directory security group that has db_owner rights to the Datastore.
After the upgrade, you can remove this account again from the security group.
Run the Ivanti Identity Director Installer.
When prompted, choose Select and install components and click Next.
In the Features section, select Transaction Engine.
If you installed other components on the same device, also select those. Their upgrade starts after you upgraded the Transaction Engine.
Start the upgrade and follow the Setup Wizard.
Repeat this process on all devices on which you installed a Transaction Engine.
