I'm looking to setup some patch management that will scan, download, and install.  After that deployment, I would like to start a timer/trigger for the next round>

Example:

1. Scan>Download>Install by IP range, nightly.

2. 4 days later deploy these updates to a different set of IP's.

3. 7 days later deploy the another set of IP's.

I'm looking to keep the care and feeding of my tiered deployment schedule to something I don't need to babysit everyday, other than looking for some initial errors.  Even those I would prefer to have emailed to me automatically.

If anyone can suggest or point me toward the correct data that would be much appreciated.
