# Limit Import

When you have more than one LTT and want to copy the limits from one LTT to another one, then use the **Import limits** function.

First, you have to copy the `50_LTT_SW\LTT Limit Files` folder, containing the limits you want to import on another LTT, to the other LTT, but not at the same location!

{% hint style="warning" %}
Overwriting the limit configuration XML files of one LTT with those from another will not transfer the limits!
{% endhint %}

Assume you currently have the following limit configuration:

![Import Before](/files/23tpc34Coxm0nxVRWnvy)

And you want to import those limits from the other LTT:

![Import File](/files/C8m8UcXcS6ds4faam0Yg)

The best praxis is to copy the limit configuration folder from one LTT to the **Desktop** of the other LTT. Once you have the limits folder copied to the target LTT, you can press the **Import limits** button in the top right corner of the dialog. A folder selection dialog will prompt you the select the limit files folder to import.

![Import Select](/files/kGoL19CNhLC5165r6MHg)

{% hint style="info" %}
All limit files (DUT types) from the import folder will be imported as long as there is a matching DUT type on the target LTT. If you want to import a specific DUT type only, then delete all other limit configuration files from the import folder.
{% endhint %}

After you have selected the import folder the limit import is performed. Once it is finished it will display a summary:

![Import Result](/files/2FeoeHsAPIwtwJJryfO3)

{% hint style="warning" %}
Be aware that importing limits will remove existing limits if they are not present in the imported limits.
{% endhint %}

After the import the limit configuration looks like this:

![Import Finished](/files/Yh1J8eLMzMquvYC9y4Xf)
