Raise forest functional level

we have 1 forest 1 domain. our 3 dc's run windows server 2003 sp2, domain functional level 2003 , our forest functional level 2000.
if raise forest functional level 2000 2003, there change in ad database itself?
or changes in ad made when ran adprep command?
raise change way dc's replicate each other?
asking question because have oracle internet directory syncs ad. if raise not affects ad itself, don't see problem sync.

hello,

i think answer misleading ad database. functional levels stored in database in attribute called "msdsbehaviorversion".

storage of functional levels

in ad ds forest, value of functional levels of domain controllers, domains, , forests stored in msdsbehaviorversion attribute. attribute present on 3 different objects in directory, each of authoritative identifying functional level of 1 of these 3 respective scopes (domain controller, domain, or forest). when enforcing domain , forest functional levels, active directory uses value of msdsbehaviorversion on appropriate object detect current functional level.
