[mssms] Automating Migration Jobs

[s kissel]

Hi
Does anyone have a tool or script to automate migration jobs from SCCM 2007 to 
SCCM 2012? Specifically, I'm looking for a way to migrate new or updated 
objects (packages) only from SCCM 2007 to SCCM 2012 on a daily or twice-daily 
basis and overwrite existing objects if they exist. The reason for this is that 
there are a lot package changes occurring in SCCM 2007 during the migration, 
and creating a migration job daily seems like an opportunity for automation.
Thanks!
