These are the deployment modes when you generate the mobile workflow package.
The New deployment mode initially generates and deploys the mobile workflow package.
The Replace deployment mode removes an installed mobile workflow package and installs a new mobile workflow package with the same name and version. The Replace deployment mode acquires a list of assigned devices for the original package, uninstalls the original package, installs the new package with the same name and version, then assigns the orginal device list to the new package, thus preserving any device assignments associated with the original package.
Use the replace deployment mode for minor changes and updates to the mobile workflow, or during initial development.
The Update deployment mode installs a new mobile workflow package with the original package name and assigns a new, higher version number than the existing installed mobile workflow package. During the update operation, a list of assigned devices is acquired from the original package, the new package is installed and assigned a new version number and then the administrator specifies device assignments for the new package from the acquired list of assigned devices. Existing notifications are preserved.
Use the Update deployment mode for major new changes to the mobile workflow.
