Hi Kash, welcome to LEEDuser—it's good to have you!
It's probably best to think of LEED-EBOM v2009 as a completely new rating system compared with LEED-NC v2.2. There are a number of credits that have similar requirements, and if you documented them for LEED-NC v2.2, you'll have a head start on LEED-EBOM, but in all cases you will have to complete new documentation. For better or for worse!
