Set-CMDeploymentType not working as expected.

Good afternoon,

I have 129 APPV5 packages I would like to modify their deployment types en-mass.

I have imported them from a script, but after this I wanted to change their DeploymentType to stream from the DP rather than download and execute.

Set-CMDeploymentType -OnFastNetworkMode RunFromNetwork

Looks to be the command, but it doesn't change the setting.

Do I need to delete all my apps and re-import them, or is this function broken for anyone else?

Thanks

Update:

Nevermind looks like it simply doesnt work.
