i want to migrate from rasa 1.1.4 to latest version , is there any guide to migrate directly without migrating to middle versions ? any idea will help to migrate . my project is big and wanted to migrate to latest version
I dont think there is a guide for migrating directly from rasa 1.x to latest 3.x.
The guide from 1.x => 2.x, which i presume you have already checked: Migrating your Rasa 1.x assistant to Rasa 2.0 | The Rasa Blog
Might need manual work in your case. Some helpful resources:
All the best
