Greetings,
I'm going to be writing a one page "What You Need to Know" brochure for
our
internal developers and application owners that bind to our AD to provide
security and other meta for their applications. We will be going direct
from 2000 to 2008 (we will do the forestprep in two steps 20K to R2, R2 to
08) and we will be conduct a hardware replacement which will complete the
upgrade's DC swapout.
I have the following bullet points so far:
------------------------------------------------------------------------------------------------------------------------------------
- Schema Extension -
This will only add attributes to the AD database schema, it will not
deactivate any attributes you are currently using. However, your
application performance may decrease while the Schema Extensions are
replicating. This will be done after-hours.
- Hardware Replacement -
We will conduct a one-for-one domain controller demotion/promotion and
will
preserve the existing IP address. This will relieve the network
administrators from having to update the DHCP scopes and DNS zone sharing
settings. the NAMES, however, will change, thus if you are binding to the
directory using a fixed host name, we advise you to take this op****tunity
to
follow best practices and update your code to reference the domain name
directly. The downtime period for each replace domain controller will be
one day, and will be performed after-hours.
- Domain Controller Security policies
Base changes in the local security policy of the Windows Server 2008
operating system may have an effect on your bind to Active Directory. The
key changes that may affect you are .....
- Global Catalog placement
In the below chart please find the names of the servers which will host
the
Global Catalog role. Please note some DC's replaced will no longer hold
the
role. {add chart}
------------------------------------------------------------------------------------------------------------------------------------
That's all I can think of, if anyone else has suggestions I would
appreciate
any input I can get.
Thanks
