Hello, I opened case 11107703 to track this issue as well. During the 'Upgrade Groups Wizard' in the SEP Management console the final action is a bit misleading. I will go through each step below.
Specify Groups - This step is okay.
Package Upgrade Settings - This is the confusing step. There is no warning or notification that when 'NEXT' is clicked on this step that the package will push. I don't ever recall seeing a wizard setup like this without a summary or a warning saying that the next step will deploy the Install package.
Update Groups Wizard Complete - This is the summary that the package has been sent. However, when the 'X' is clicked the wizard asked if you wanted to cancel the wizard. Canceling the wizzard is too late at this step and that prompt may become confusing if the Installation Package has been removed or not.
I am reqeusting that a 'warning' or another summary screen be inserted before the final 'Finish' step.
Warining Example "To change these settings, click Back. To apply these settings Ckick Next."
