Here are the steps you can perform to make a duplicate copy of a task sequence in MDT 2010. You might do this for example if you have a customized task sequence that you want to use as a template for creating additional task sequence you can then customize.
- Create a new task sequence.
- Open Windows Explorer and locate the file system folder associated with your original task sequence, for example the folder C:\DeploymentShare\Control\OLDID, where OLDID is the Task Sequence ID of your original task sequence.
- Copy all the files contained in this folder such as TS.XML and Unattend.xml to the similar folder associated with your new task sequence, for example C:\DeploymentShare\Control\NEWID.
- Open the Deployment Workbench and customize your new task sequence as desired.
