contentstack-express versions running in 1.0.x or 3.0.x will need to perform the following steps to upgrade to v3.1.x:

1. Install [email protected] using npm install -g contentstack-cli.
2. Go to your project folder and run npm install -s [email protected].
3. Create a backup of the _content folder and then delete it before proceeding further.
4. Set the environment on which you wish to sync the content, for example, $ export NODE_ENV=production (Linux distros) OR $ set NODE_ENV=production (Windows).

Note : The environment variable used here is used to determine which configuration file to pick from when contentstack process is run.

5. Use the contentstack sync command to get all the data from Contentstack.

Warning : The latest version of the framework can be used only with V3 stacks. If you are still using V2 stacks, you need to first upgrade your stacks to V3 before upgrading the framework. To upgrade your stacks from V2 to V3, please send an email to our support team at [email protected].

Also, while moving from v1.0.x to v3.x.x, the default contentstack-express templating has been changed from ‘swig’ to ‘nunjucks’.
