It's probably best to recreate them, even if you somehow get them to migrate 
successfully you lose all the functionality you would get with ConfigMgr 2012 
R2/MDT 2013 because the backend XML isn't there.

It does look like it is possible, but again I wouldn't recommend it.

Looks like it's not possible to migrate any MDT integrated task sequences 
though. You have to remove those steps first.

Subject: [MDT-OSD] Migrating Task Sequences from CM 2007 to CM 2012 R2

I'm wondering what I've gotten into and how to get out of this catch-22.

We're migrating our CM 2007, with MDT 2010 task sequences over to CM 2012 R2 
with MDT 2013 integrated.

I set up the first test migration job and selected to migrate one of our 
simpler OS deployment task sequences.  The job migrated everything except the 
task sequence itself.  From what I'm finding is that it failed because it is an 
MDT 2010 integrated TS.  All of the info I find though is for migrating to CM 
2012 and say to upgrade my original task sequence to MDT 2012 integration 
before attempting to migrate them.

But, since MDT 2012 is not supported with CM 2012 R2, wont that fail as well?  
I cannot upgrade my original task sequences to MDT 2013 because that doesn't 
support CM 2007.

How should I migrate my task sequences from CM 2007 over to CM 2012 R2?

Thanks
