How can I migrate registry keys from one location on the source to another on the destination

if you want to migrate registry keys from one location to another
(provided that they are detected) then use the following code in a
custom XML file

<?xml version="1.0" encoding="UTF-8"?><migrationurlid="http://www.microsoft.com/migration/1.0/migxmlext/WNB_move_reg_keys"><!-- WNB_move_reg_keys.xml is basically a customized version of MigUser.xml --><_locDefinition>  <_locDefault _loc="locNone"></_locDefault>  <_locTag _loc="locData">displayName</_locTag></_locDefinition> <!-- This component migrates Old Reg Keys and moves them to NEW locations provided that the key exists --><componentcontext="User"type="Application">  <displayName _locID="regkeymove_user">Move old reg keys to new location</displayName>  <rolerole="Settings">   <detects>        <detect>        <condition>MigXmlHelper.DoesObjectExist("Registry","HKLM\SOFTWARE\CUSTOM [CUSTOMval#1]")</condition>        </detect>   </detects>   <rules>        <include>        <objectSet>        <patterntype="Registry">HKLM\SOFTWARE\CUSTOM [CUSTOMval#1]</pattern>        <patterntype="Registry">HKLM\SOFTWARE\CUSTOM [CUSTOMval#2]</pattern>        </objectSet>        </include>        <locationModifyscript="MigXmlHelper.ExactMove('HKLM\SOFTWARE\CUSTOM [PrevCUSTOMval#1]')">        <objectSet>        <patterntype="Registry">HKLM\SOFTWARE\CUSTOM [CUSTOMval#1]</pattern>        </objectSet>        </locationModify>        <locationModifyscript="MigXmlHelper.ExactMove('HKLM\SOFTWARE\CUSTOM [PrevCUSTOMval#2]')">        <objectSet>        <patterntype="Registry">HKLM\SOFTWARE\CUSTOM [CUSTOMval#2]</pattern>        </objectSet>        </locationModify>   </rules>  </role></component></migration>

this code checks if the following registry key exists HKLM\SOFTWARE\CUSTOM\CUSTOMval#1 and if it does, it migrates the following two registry keys from the SOURCE pc

HKLM\SOFTWARE\CUSTOM\CUSTOMval#1
HKLM\SOFTWARE\CUSTOM\CUSTOMval#2

to the following locations on the DESTINATION pc

HKLM\SOFTWARE\CUSTOM\PrevCUSTOMval#1
HKLM\SOFTWARE\CUSTOM\PrevCUSTOMval#2

Note: if you are using a 64 bit OS with a 32bit application (X86) that you’ll probably want to change the path statements

for example, change

HKLM\SOFTWARE\CUSTOM [CUSTOMval#1]  

to

HKLM\SOFTWARE\Wow6432Node\CUSTOM\[CUSTOMval#1]
