Since we are getting computers that will not work on WinPE 2.1 due to network drivers not been support and we are not ready to upgrade to 7.5, we decide to follow this article: http://www.symantec.com/docs/HOWTO85100 which shows an upgrade steps to WinPE 4.0.
So I start to follow the Article and realize there is a lot of manual process and since this has to be done in all packages servers and SMP, and in an environment with more than 5 packages servers is enough to have some automation in place.
So I decide to write a PowerShell to take care of the manual steps.
Remember: this works on my environment, which means it might NOT works on yours, so I recommend you to look at the code before running. (This code has no warranty that will work)
Before running the code, there are couple checks you need to do:
I recommend running from the PowerShell interface: - Start > Accessories > Windows PowerShell > Windows PowerShell
The code will
Once the code is done, you will need to modify the Bootwiz Drivers packages using the console (the info is on the Article http://www.symantec.com/docs/HOWTO85100)
This code was done in couple hours so if there is improvements, please post so we can have this process as automated as possible :)
