This article is for existing Lightning Forms or Lightning Tools Actions customers who are upgrading to Lightning Tools Forms Studio. The migration process was updated in February 2025 to this streamlined method.
Migrate customized Lightning Forms
- In LT Forms Studio, create a solution from scratch using the site URL where you have already customized forms.
- Create a new Dossier, and add your existing Main list and any Sublists and Sublibraries (choose Select Existing List).
- Add any other existing lists under Other Lists & libraries in the same way.
- Add any existing Pages, especially if they contain Lightning Tools Actions.
- All of your existing Form customizations and Actions should now be migrated into a Solution. This is now your Production solution.
Site Collection App Catalog
If you go to the Site Contents of your site, you will notice that during this process, a Site Collection App Catalog was created for this site, and your solution was added to it as a SPFx app. You will also see the app listed in the Site Contents. Do not delete either of these apps.
