Running the node manager upgrade tool silently

As an alternative to running the node manager upgrade tool interactively, you can run it silently from the command line.

Before you begin

You have installed the new node manager.

Open a command line as an administrator and navigate to the directory <new node manager installation directory>/nm/upgrade.
By default, the node manager installation directory is located here: C:/spotfire/nodemanager/<version number> (on Windows) or /opt/spotfire/nodemanager/<version number> (on Linux).
To see the parameters that the upgrade tool will use, do one of the following:
- On Windows, type upgradetool.bat --h.
- On Linux, type upgradetool.sh --h.
The parameters are listed on the command line. Review the list of parameters and specify any that are applicable for your node manager.
Run the upgrade command using the desired parameters. For example:.
```
upgradetool.bat --cmd --from old node manager installation dir --to new node manager installation dir
```
The node manager upgrade tool runs silently.
