Increase performance in file migration

This method ultimately increases the performance of Autodesk Inventor.

This method takes longer than selecting an entire project at a time for migration. However, it is more efficient. It loads each part and subassembly into memory one by one before freeing up the memory for the item. The software can open files without migrating them, so it reduces the time to open an assembly model.

1. Note: To ensure the full benefit of memory saving mode, migrate all of your R10 and earlier files using Task Scheduler.
   On the Start menu, click Programs Autodesk Autodesk Inventor [version] Tools Task Scheduler.
2. In the Autodesk Inventor Task Scheduler window, click Migrate Files.
3. In the Autodesk Inventor Task Scheduler window, right-click, and select Create Task Migrate Files.
4. In the Migrate Files dialog box, in Project, specify the active project.

   If a vault project is active, then files are migrated from the vault. If a non vault project is active, then files are migrated from the local hard drive.

5. Click Add Folder to migrate two or more part (.ipt) files.

   To include subfolders, click to place a check mark in the Recursive column. In the File Name Column, click the down arrow to specify the file type within the folder to migrate.

6. Repeat the previous steps for all of the subassemblies (not the main assembly).
7. Repeat the steps for the main assembly.
8. Repeat the steps for the drawing (.idw) and presentation (.ipn) files.
9. Select the files in your migration list, and click Options.
   • Turn on Total Rebuild.
   • Turn on Skip Migrated Files.
10. In the Task Properties box, enter a task name and a time-out threshold.
11. Specify a schedule, or select the Immediately option.
    Note: For optimal performance, close all Autodesk Inventor sessions before you run your task. Do not start a session while a task is running.
12. In Log File, leave the checkbox selected for the default located in Documents and Settings\(user name)\Local Settings\Temp\Task Scheduler.log

    or

    • To overwrite the default, enter a file name. If the log file does not exist, a log file unique to the task is created.
    • Click Browse to find and select an existing file.
    • To specify no log file, clear the checkbox.
13. Click OK.

    If it is the first task you create during the current session, the Authentication dialog box displays. Enter your Microsoft Windows log in name and password.

The task is displayed in the task list. You can close the Autodesk Inventor Task Scheduler window. The task runs as scheduled.

The log file reflects the success or problems in the migration.

Migrating just the main assembly, the software loads every part and subassembly separately into memory, including recurring parts and patterned assemblies. This technique can result in out of memory and stability issues with large assemblies. Windows on a 32-bit operating system can allocate a maximum of only 2 GB of memory to each CPU process. This 2-GB limit can be spread over RAM or the page file. Large assemblies with component patterns can produce major issues.
