Installation guide

Migrating and Customizing

If you have a previous version of AutoCAD LT installed on your system, you can install a

newer version of AutoCAD LT and keep other versions of the program on the same system.

This is called a side-by-side installation. If you've purchased an upgrade version of AutoCAD

LT, you are required to uninstall the previous version within 120 days of installing your newer

product. See your license agreement for more information.

In this section, you learn about migrating from previous releases, using customized files from

previous releases, and locating customized files.

You can use the following tools to migrate settings and files:

and aliases). The Migrate Custom Settings dialog box is displayed when you

start the product for the first time. You can also migrate settings later from

the Start menu (Windows).

MNS) to the CUI format while leaving the original MNU or MNS file

unchanged. Migrating user interface elements, transferring data between

customized files, and customizing user interface elements are simplified in
