This was released in Statistica 13.5 .
This feature is provided through the following script: C:\Program Files\Statistica\Statistica 13\SupportScripts\UpdateDeployedWorkspaces. Open this script and read the green text for instructions on updating nodes. These nodes must be stored inside a Workspace. And the Workspace is saved in Statistica Enterprise Manager.
This idea requires very good specification based on use cases.
The need is definitely there, especially with custom nodes which require code maintenance.
For such functionality to work well the Nodes require to have "class IDs" (of the parent custom node master from which the particular node instance originated) as usually we create multiple instances of the same "node class" and the code of the node is maintained somewhere.
It might be possible good to have a "poor man's" (or basic) source control of the "node class" in Enterprise + SDMS (or even to enable connection of node source control to SVC systems such as Git, SVN, TFS) ?
Would be nice to be able to optionally update the options/parameters (DMI) as well.
