When updating an app, you were able to choose either to replace the current version or to create a new major version, not retro compatible meaning you had to create a new project to get the newer model (audit trail will not migrate).
After recently releasing the update model feature ( Update already uploaded models to a newer version ), we've added a third option to create a minor version that will:
Create new projects on this latest version
Give possibility to update projects created with a previous version to the latest one while keeping the audit trail.
How to update my App models to a newer minor version?
To update your App with the Update model feature compatibility, you need:
A blank project where you uploaded the updated Excel files
A CSV resolver file, that will resolve all conflicts between the previous version and the updated version you will upload.
Then open your app in the AppBuilder of the administration. Into the part "2. App Version", choose "Update current version".
In "Select source project", select the project you created with the updated Excel files.
Then in "Conflict Resolver CSV", upload the CSV you prepared with the resolution of the conflicts (you can select the delimiter).
Then click on the Update App button. You will see that your app version will change from, for example, 1.0.0 to 1.0.1.
Create a new project from this updated app
When creating a new project from this app it will use the latest version, meaning that it's version 1.0.1 that will be used by default with no possibility to select a prior minor version.
Update an already created project from this updated app
Once your app is updated with a new version, you can update your app project created from an older version.
A new button will appear within your project on the action bar. Simply click on it to start the update process.
This process will keep the audit trail entries of your project while updating the source Excel files. It will require reloading your project at the end of the process.
Please note that if you are updating more than one version (for ex. from v.1.0.0 to 1.0.5), the update process will be launched sequentially several times (5 times in this example).
