Migrating GPOs to RES PowerFuse (Part 1)

When delivering RES PowerFuse Pilots, the process that typically takes the most amount of time is the manual creation of existing user Group Policy Objects (GPOs). With a Pilot (and Proof of Concept) deployment a clean OU within AD is a mandatory requirement. This ensures that we have a safe haven to place the Pilot user accounts to ensure that they are not impacted by any existing GPOs and logon scripts. Adding RES PowerFuse on top GPOs and logon scripts is going to slow the logon process down and is contrary to what is trying to be achieved!

In an ideal situation, the Pilot customer will know which GPOs and which settings need to be applied to which user groups/OUs that are partaking in the Pilot. After the required ADM/ADMX files have been located, the required settings can slowly and painfully be transcribed into RES PowerFuse as User Registry Policies.

As a GPO is made up of one or more ADM or ADMX files, the Group Policy Management Console (GPMC) does a fantastic job of consolidating these in to a single view and a single resulting GPO. Unfortunately, RES PowerFuse doesn’t do a  great job of this. We can upload individual .ADM and .ADMX files but the result is numerous User Registry Policies for what was a single GPO. Let’s take Microsoft Office 2007 as an example. There is a separate ADM template for each Office 2007 application. In the GPMC we see these in a single view and can manipulate the settings under one Group Policy Object. With RES PowerFuse we need to upload each ADM template and create a User Registry Policy per ADM template. Now we have five User Registry Policies – one each for Word, Excel, Outlook, PowerPoint and Access rather than one. If we need to provide different settings to five groups of users we’ll need 25 User Registry Policies rather than 5 GPOs!

As an option, we can export the User Registry Policies from the RES PowerFuse management console to individual .REG files. The original User Registry Policies can be disabled and a new User Registry created. All the .REG files can be merged to create a single User Registry settings equivalent to our single GPO. However, by doing this we do lose the ability to “browse” the ADM file to turn settings on an off like within the GPMC.

The original ADM files shipped with Windows Server 2000 and Windows Server 2003 were quite large but there weren’t too many of them. With the release of Windows Server 2008 the file format changed to XML and Microsoft took the opportunity to split the large large ADM files in to many smaller ADMX files. On my test machine, I have 147 ADMX files on a basic install of Windows 2008. Now that equates to lots of User Registry Policies in the RES PowerFuse management console!

If getting the Pilot (or PoC) up and running as quickly as possible is a must, this manual process is going to add a vast quantities of time configuring the User Registry Policies. Manually transcribing the GPOs does allow for a review and consultation to be performed which is no bad thing considering there may be years of GPO bloat. What if there was a quicker method to actually getting the existing GPOs into RES PowerFuse? Would replicating existing GPOs “as is” without the review and consolidation be a good starting point? Would it be of benefit?
