Please note the related article: Importing_from_Nexus_Mod_Manager:_Things_to_consider.

Prepare and Install Vortex

Ensure your current Mod Manager isn’t downloading or installing anything and close it. In the case of Mod Organizer, if you want to save files in the overwrite folder ensure you either create a new mod or add them to an existing one.

Importing your mods

Now you have the current game selected, head to the “Mods” section. Along the toolbar at the top, you will find “Import from…” which will show the import options available.

On the first page of the Import Tool, Vortex will attempt to auto-detect the mod manager you’re importing from. If it can’t find it, or you have more than one version of the mod manager installed, you can change is the mod manager install path.

Step 2 will show a list of currently installed mods in NMM. You can manually change the “Import” drop-down next to each file in order to stop Vortex from adding the mod. Another important checkbox is found at the bottom left - “Import Archives” will pull the original archives for the selected mods. This is highly recommended because you may need to reinstall the mod from its archive if you remove your old mod manager. Archives will be stored in the Vortex download folder, which can be defined before running this tool if required.
