Preparing to Upgrade a Server Only Installation
* 
Only Windows Administrators who are also Modeler Administrators can perform Modeler upgrades.
For information about upgrading a previous version of Modeler, see Upgrading Modeler.
If you have installed Modeler to the default location, the Release Notes reside in the following location.
For 64-bit versions of Windows:
C:\Program Files(x86)\PTC Integrity Modeler\Modeler\System\PrintableDocs
For 32-bit versions of Windows:
C:\Program Files\PTC Integrity Modeler\Modeler\System\PrintableDocs
* 
Before you upgrade a Server Only installation, ensure that you backup your repositories and read the Modeler Release Notes.
If the server runs a server-based floating license, ensure that you have obtained the appropriate replacement licenses from PTC. After upgrading Modeler, you must start License Manager and replace the license file.
If you choose to install Web Interface, a dialog will be displayed that allows you to set the password for the PTC-IM-WSU account. If you have previously changed the default password for this account (which is recommended), ensure you re-enter your chosen password.
