2.4 Upgrading an Existing Installation
Upgrading an existing Patran installation is a manual operation and requires the following steps:
1. Follow the steps in Creating a New Installation. This will create a parallel Patran directory. For example,
dir c:\MSC.Software\Patran
06/25/98 12:16p	 <DIR> 20xx
06/25/98 12:16p	 <DIR> 20yy
If you do not have enough disk space for parallel directories, uninstall the existing installation. But first make sure to copy the customization files listed below, however. See Uninstalling, 25.
2. Copy the following customization files from the old installation directory to new installation:
• p3_printers.def
• p3_trans.ini
• p3epilog.pcl
• p3toolbar.def
• p3quickpick.def
• settings.pcl
• p3manger_files\*.cfg
• p3manger_files\*\*.cfg
3. Copy any customized template databases from the old installation to a staging area and open each one by running Patran from the new installation. The databases will be converted to the new database schema. Once this is complete, you can copy them to the new installation area.
4. Once you have completed testing the new installation or are comfortable using the new version, you can uninstall the previous installation.
