How to clean out old OpenManage driver packages and replace them in Configuration Manager 2012

To clean out the imported OpenManage driver bundles from ConfigMgr and replace with newer or the same versions.  This works for any version of OM driver bundles but for this example I will use the last version and latest version at the time of this writing as examples (OM7.3.2 and OM7.4).  Some of these delete folder steps may need to be done on each DP.

1. Write down the Package ID first for each one drive package, or take a screenshot.  Then delete the Driver Packages and folders.
2. Go to the same driver folders labeled as "Dell PowerEdge Drivers OM7.3.2" in the Drivers sections in ConfigMgr.  Highlight all of the drivers listed, right click and delete them.  Then delete the folder as well.
3. Remove the folders labeled as "Dell PowerEdge Drivers OM7.3.2" also from both Drivers Packages and Drivers.
4. Go to the ConfigMgr Installation location which is normally "C:\Program Files\Microsoft Configuration Manager".  From here you will go down and delete the OM7.3.2 folders for the same versions you deleted from inside ConfigMgr in the following folders.
1. "\OSD\Lib\DriverPackages\Dell\PowerEdge\"
2. "\OSD\Lib\Drivers\Dell\PowerEdge\"
5. Go to the drive where your DP Shares are located.  For example, if they are on the E: drive you would go to "E:\SMSPKGE$\".  If they are on the G: drive you would go to "G:\SMSPKGG$".  Delete each Package ID folder that you copied back in Step 1 for each Driver Package.  These folders may just be empty shells at this point.

Now the old versions are cleaned out and you are ready to import new versions.  These driver packages can only be imported from the Dell System Management Tools and Documentation (SMTD) iso.  Do not use the SBUU, CDU, or SUU iso or your drivers will not be imported correctly.

1. First, mount the SMTD 7.4 iso in Server 2012 by double clicking on it so that it will appear like a DVD drive.
2. Right click on Drive Packages and select the "Dell Server Driver package\Import Dell PowerEdge Server Driver Packages" option.
3. Select the drive letter that the OM7.4 iso is mounted it.
4. Select the server models and OS versions you want to import and let it run.
5. Right click on each driver package that you imported and go to Properties. On the Data Access tab, check the box "Copy the content in this package to a package share on distribution points".  Press OK.
6. After each of those is done, right click on each driver package and Distribute Content.  Select your DPs and then give it some time to distribute.  The amount of time will depend on # of DPs, locations, network, etc.
7. Check the Content Status for an updated date and time and green pie chart.  You can also verify distribution to each DP by going to the SMSPKGdrive$ folder and verify the PackageID folder is created and drivers are there.

********* Note here*********  I have noticed that drivers do not always fully distribute.  Your SMSPKGdrive$\PackageID folder may only have one GUID sub-folder.  In this case, just Update the Distribution Points again for the same package and make sure the content status shows success.

8. Now just go back to your Task Sequences, Edit, and on the Apply Driver Package step just add the new package.
