I'm unsure if I provided sufficient information, so here's a quick overview about what we currently do and what I need to do:
There are two primary tasks that we are currently performing - migrating users from XP to 7 and recloning Win7 machines due to bugs or security vulnerabilities. Since we are mostly already migrated to Win7 from XP, our primary goal is to integrate automatic user state migration, with primary emphasis on documents and secondary emphasis on settings, etc, into our Win7 reclone process. We use offline installation with WinPE, booting from flash boot media, and recently changed over from SCCM 2007 to SCCM 2012 without issue.
My methods are relatively flexible - the main requirements are that the user state information gets migrated and the OS re-installed; all other variables are fine to change, if a solution requires any of our current process to be modified.
Thanks for any help, or direction anyone can point me in.
