Wishing to upgrade Active Directory

Wishing to upgrade Active Directory

We are currently working with Build 8203 and it is synching with Active Directory 2003, with a domain account. Single access log on (network authentication) and asset scans are working.
 
We wish to upgrade Active Driectory and were wondering?
 
1) Does build 8203 support Active Directory 2008 or Active Directory 2012
2) Do we have to change anything in our configurations? 
 
Thank you
