Logic board replacement (swap in a mid-2010, 2.66)

Checked this thread first: Upgrading logic board with mid 2010 model

It did not seem very helpful, in that there is no clear answer there.

From what i can gather, a mid-2010 MacBook Pro 13" 2.66 GHz Logic Board will directly replace my current board. Chipset locations, mounting holes (through the PCB), and ports are all identical and there should be no issues mounting to my mid-2009 case.

Question:

1- Do the refurb'd boards sold here by ifixit come with the serial numbers wiped, so that I can restore my current serial number to the new board (makes integration to the iCloud and iTunes store vastly simpler)?

2- What kind of software issues will I need to be prepared to mitigate? (Note: my current MBP now a bit older, is a 3rd generation image that started on an Intel MacBook in 2006, transferred via HD swap to a newer MacBook in 2008, and then finally migrated, again via a HD swap to the current machine. Along the way I have upgraded the OS from 10.5, to 10.6, yadda, yadda, yadda....and copied the image to bigger HDs for swap in as well. I do not fear software issues, just want to know what to expect.)

Thanks!
