Hello world!


ConfigMgr - Current Branch ServiceConnectionTool/ Upgrade Content Validation Offline

 

Hello, my name is Terrance B. and I'm a Premier Field Engineer. This blog post is about an adventure I had downloading and copying Current Branch upgrade content between networks A, B. manually.

This is the process I went through doing ConfigMgr Offline Upgrades w/o using removable media.

I verified I had a clean download-- no (redist) errors in the log using the ServiceConnectionTool. The upgrade offline media is around 22GB of data and I was missing 2 GB of content.

Here is where the fun comes in some proxy can/ will remove certain file extensions, executables or think it's malicious.

I ran into the following errors:

  • Importing the upgrade bits, the process fails saying files are missing (ServiceConnectionTool.log)
    • Downloaded new bits while monitoring the log for errors
  • Importing the upgrade bits failed due to FIPS being enabled
    • Disabled FIPS and the import was successful
  • Installing the upgrade, the process fails, and the log shows a list of files not found.
    • Replaced the files that were not found and re-ran the process, it failed again on different files not found.

Here is how I solved the problem and saved some valuable time!!!

I have a PowerShell script that will hash out all files including sub folders and output to a CSV file. Import the CSV file into an Array and compare Array B to original Array A from network.

If there is a file difference it will output on the screen, if everything matches up no output on the screen.

 

#Steps:1 Create an Hash File of the content, output to CSV file .

# GET A CSV FILE FOR EACH DIECTORY FILE HASHES  (NETWORK A)

Get-ChildItem -Recurse C:\Work\Dir1 | Get-FileHash -Algorithm SHA256 | Export-CSV -Path c:\Work\HASH_Dir1.CSV

 

# GET A CSV FILE FOR EACH DIECTORY FILE HASHES  (NETWORK B)

Get-ChildItem -Recurse C:\Work\Dir2 | Get-FileHash -Algorithm SHA256 | Export-CSV -Path c:\Work\HASH_Dir2.CSV

 

#Step:2 Copy the CSV file from Network A to network B and Import them into an Array

# IMPORT EACH DIRECTORY FILE HASH INTO AN ARRAY

$Dir1Arr= import-csv E:\work\HASH_Dir1.CSV

$Dir2Arr = import-csv E:\work\HASH_Dir2.CSV

#Step:3                             #  CREATE AN ARRAY OF DIFFERENCES BETWEEN THE FILES

$diffArray = Compare-Object -ReferenceObject $Dir1Arr -DifferenceObject $Dir2Arr -Property Hash

 

#  LOOP THROUGH THE DIFFERENCES AND MATCH THEM WITH THE FILE ENTRY

ForEach ($diff in $diffArray)

{

If ($diff.SideIndicator -eq "<=")

{

$bolDir1 = $true

$Match = $Dir1Arr| Where-Object {$_.Hash -eq $Diff.Hash}

$Match.Path + " Has a hash of " + $Match.Hash

}

Else

{

$bolDir2 = $True

$Match = $Dir2Arr | Where-Object {$_.Hash -eq $Diff.Hash}

$Match.Path

$Match.Path + " Has a hash of " + $Match.Hash

}

 

 

}

 

Example of both arrays match up, no output 

PS C:\Users\terranceB\Documents> C:\Users\terranceB\Documents\HASH_CHECK.ps1

PS C:\Users\terranceB\Documents>

Example of output difference I added a file to Dir2, so it would show an output result

PS C:\Users\terranceB\Documents> C:\Users\terranceB\Documents\HASH_CHECK.ps1

E:\Work\Dir2\TEST-TerranceB.docx

E:\Work\Dir2\TEST-TerranceB.docx Has a hash of E7B6B5EF4BE60D5BF2B288B93377DDEB7

If you have one file that is missing manually copy the missing file, but if it more than 5 files/shares and some of the directories go as far as 8 layers deep I would recopy all the content from a good source.

Using removable media, the only problem you may run into is Antivirus scanning the content on your server and striping out files.
