Introduce New Child domain and move machines from root domain to child domain

hello everyone,

here scenario, 

current setup looks below:

root domain: abc.com

domain , forest functional level : windows 2008 

domain controllers: 4 dcs, gc , operating system windows 2008 r2

we have exchange 2010, lync server, wsus, sccm 2007 , sharepoint in root domain

requirement: 

we have requirement introduce new child domain 'xyz.abc.com' , migrate qa/dev machines root domain child domain.

domain controllers in child domain of windows 2008 r2.

i have few questions regards scenario.

questions:

if introduce new child domain  'xyz.abc.com' in root domain 'abc.com', adversely affect existing setup ? mean, there issues exchange, sccm etc ?

do need raise functional level windows 2008 windows 2008 r2 ?

suppose, if introduce new child domain, able use wsus , sccm root domain managing migrated machines in child domain ?

how should go configuring dns servers in child domain ? installing 2 domain controllers start with.

how should place fsmo roles in 2 dcs in child domain ?

what should nic config on child dcs ?

child dc1 - preferred dns ip : child dc1 ip, alternate dns : root dc 1 ip

child dc2 - preferred dns ip : child dc2 ip, alternate dns : child dc 1 ip

will alright ?

what should dns ips migrated machines root domain child domain ?

referred dns ip : child dc1 ip, alternate dns : child dc 2 ip

will work?

anything else need aware of before going ahead , promoting child domain controllers ?

thanks in advance pointers , help.

if need ask question in multiple forums or other forum, please advise.

thanks !

well if machines , not users exchange should not impacted.

sccm need configured have relevant credentials , settings new domain , able inventory , manage machines.

do need raise functional level windows 2008 windows 2008 r2 ? - not unless need of additional functionality provided r2

suppose, if introduce new child domain, able use wsus , sccm root domain managing migrated machines in child domain ? - yes - need configured correctly credentials in the new domain

how should go configuring dns servers in child domain ? installing 2 domain controllers start with. - i configure both dc's ad integrated dns zones , point each dc (some discussion on around if still best practice). , secondary other dc. computers need setup these dns servers primary , secondary. setup dns zones replicate whole forest, or setup forwarders etc - depends on size of environment , network topology.

how should place fsmo roles in 2 dcs in child domain ? forest fsmo stay in forest, , put roles on 1 dc in child domain seems small domain
