I have Two Neoload Projects (Two are individual Project1.nlp, Project2.nlp)
Now how to merge/copy the Created Script from Project1 to Project2.
You can use the export/import feature in NeoLoad but first of all, make a backup of your two projects by zipping the project folders.
Then open your project2 in NeoLoad and go to menu "File-->Import project". Browse to your project1.nlp and follow the instructions.
