When upgrading the domain from 2003 to 2008 r2, what are the impacts on the clients

-

here our current situation

beginning:

adprep /forestprep , adprep /domainprep have been runned

 

3 dc 2003 gc

2 dc 2008 r2 gc

all 5 servers dns

server 2003a , 2003b configured dns on clients , server.

 

what do:

1-move fsmo roles 2008 r2 servers

2-remove gc server 2003c

3-do dcpromo remove ad 2003a (and gc), 2003b (and gc) , 2003c.

reassign ip of 2003a , 2003b 2008d , 2008e 

at end:

2 dc 2008 r2 gc , dns left

 

our concern is: happens clients , services authenticated on decommisioned servers. need reboot or restart netlogon?

is there else missing?

nothing happen clients , services, not need restart anything. why want reassign ip, new dcs can have different ip addresses, can provide clients new dns ip addresses via dhcp, servers have static assignment have change that (there nothing wrong reassigning ip addresses, wanted pointed out not have to).

you should finish 2 dc beign gc , 2 dns servers installed on dcs (having 1 dns not recommended)

additionally after migration should have in opportunieties of rising domain level , forest functional level windows 2008 r2

with kind regards
