Citrix UPM to FSLogix

#Requires -RunAsAdministrator
<#
Written by David Ott
This script will convert Citrix UPM profiles to FSLogix .vhd profiles (you should be able to edit it to do vhdx as well)
Pay attention to all of the commented areas.  It uses diskpart to create/mount/dismount the .vhd file, and
robocopy to copy the UPM profile to the .vhd.
Once executed (assuming you have edited $newprofilepath and $oldprofiles to match your environment) it will give you a list of
profiles to convert.  You can then select which profile(s) you wish to convert to FSLogix profiles.
You could also edit this script to use hyperv commands to create/mount/dismount the vhd/vhdx files instead of diskpart if you have
the hyperv module installed.
Before using in production test!!
#>
# fslogix profile path
$newprofilepath = "\\server\fslogxprofiles" ##### FSLogix Root Profile Path
<#
upm profile path - our production UPM root folders are username.domain, and the actual Windows 7 profile lives under
v2x64\UPM_Profile:
\\server\share\%USERNAME%.%USERDOMAIN%\!CTX_PROFILEVER!!CTX_OSBITNESS!
this would have to be edited based on environment - the main thing is to have it have the full path to all of the actual UPM_Profile
directories
#>
$oldprofiles = gci \\oldserver\upmprofiles | ?{$_.name -like "*.$env:userdomain"} | select -Expand fullname | sort | out-gridview -OutputMode Multiple -title "Select profile(s) to convert"| %{
Join-Path $_ "v2x64\UPM_Profile"
}


# foreach old profile
foreach ($old in $oldprofiles) {
<#
Since I know that the folder has the username in it i get that and save it to the sam variable, and use that to get the user's sid
then save that to $sid.
You will most likely have to edit the $sam line to pull the username out of the old profile path.  Play with the string and
split-path until you nail down just the username.  For instance let's say your current profile path is
\\server\profileshare\username\v2x64\UPM_Profile  you could do something like this
$sam = (($old -split "profileshare")[1] -split "v2x64")[0] -replace "\\",""
That splits the string at profileshare, and selects the 2nd part (0 would be the first) which is \username\v2x64\UPM_Profile
it then splits that again using v2x64 and selects the first part (remember 0 is the first) which is \username\
Finally it replaces the "\" characters (you need to match \\ as \ is a special character the first slash just says to use it as a
string) with nothing... leaving you with the username.
