With the new 2012 import/export functionality, the new file format is “.zip” file. This compressed file contains not only the task sequence XML can also include any dependencies to the task sequence like a boot image. While this is awesome for migrating between a test and production ConfigMgr 2012 environment, it does not help if you are trying to import task sequences from a disconnected 2007 environment.
In my consulting practice, we do a lot of OSD implementations using a base set of task sequences that we already have pre-configured. Once at a customer, we customize our base templates for the specific project and then export the XML or ZIP to the project documentation. Well today I was at a client that we had previously done work for and they had already performed a 2012 upgrade and removed their old 2007 environment. However, they did not migrate any of the OSD and were looking for us to re-implement OSD in their new environment. Instead of importing our canned OSD for 2012 and then customizing for their needs, we wanted to use the customized 2007 task sequences we had implemented for their old environment. The first problem, however, was the only copy of those were from the archived XML from our project files we had left them. The second is that you can’t import that XML through the 2012 console. Not to worry though, we can still make it work.
The 2012 exports are just compressed files full of the resources, some configuration files, and then the task sequences XML. This 2012 task sequence XML is not the same as the old 2007, but we are able to insert the 2007 XML into the appropriate spot to make it useful. This enabled us to save a bunch of time from recreating the old TS logic. The following is a quick example of how this works.
Start with a 2012 exported task sequence. This is in .ZIP format.
Once exported, open the zip file and navigate to the task sequence folder and copy out the object.xml
Open the object.xml file and you will see a lot of new xml, however, scrolling almost to the end of the file you will find a section with embedded task sequence XML.
This XML is the same task sequence XML as you have in a normal exported task sequence from 2007, however you need to be sure only to grab the appropriate XML nodes and not the whole task sequence. To do so, in the old 2007 XML, copy the nodes and data from the sequence xml node:
and paste it into the object.xml in the CDATA section in the 2012 XML replacing the existing embedded sequence node:
You don’t have to worry about the text/line formatting. Save the file and then copy it back into the .ZIP file. You can then import the ZIP file into your 2012 environment and adjust your referenced objects accordingly. This is great when you have a master task sequence of custom tasks and you just would like the ability to copy/paste them into your new 2012 task sequences. One thing to remember is that your old task sequences were built on the package/program model for software installs. If you are leveraging the new applications model (which you should be) you will have to recreate those specific tasks anyways.
It seems that some people are having problems importing. While I’m not sure as to what they are seeing specifically, I found that the best option that worked for me was to create a blank default task sequence (not a MDT task sequence) to use as the export template from 2012. I grabbed the sequence node from the old and inserted it into the new, replacing the embedded sequence xml node. I don’t see why you couldn’t grab below the sequence node as well (after <sequence version=”3.00″>). It think may address some of the users’ experiences of having 3.10 as a sequence version. Hope that helps and keep sharing your experiences.
