Hi,
I've a requirement to change my Schema master to a different DC (2003
environment) for Exchange 2007 planning.
I know the commands to move this.

However i wanted to double check if i need to be aware of any issues with
just moving it?
Does it cause any disruption to anything?
Can it sit on the same box which is a GC?
In short - is there any considerations i need to think about when moving the
schema master role?

Many thanks.
Dave.

No gotchas that I can think of. I would ensure the DNM is also on the same
machine, and yes, make it a GC. If you have multiple domains, the GC cannot
be on the IM, but if you have only one domain, all DCs are recommended to be
GCs.

I will say that if you have any DCs that are multi-homed (with multiple NICs
and/or IPs, or RRAS installed), that will definitely cause problems.

Curious, why do you need to move it?

I dont think that ther shall should any problems in tranfersing the
schema role to another DC . The most important this is you should me a
member of Schema Admins group. Please see this link which can be
helpful

Many thanks.
And to answer the previous question it is for Exchange 2007 pre reqs. (Not
my installation but the team doing it have flagged the schema master DC is
not in the same sit as the Exchange server and so fails on setup). I don't
believe that to be the case but i'm happy to change if there are no issues
by doing so which sounds about right.
Thanks,
Dave R.

Fails on setup? It shouldn't really fail. Or do you mean the schema updates?
Schema Updates are best performed on the Schema master itself, not from
another server or workstation. Otherwise there's network traffic involved
for the changes to traverse, as well as that if done from a non-Schema
Master, there's replication lag.

If the Schema Update is failing because it is in a different Site, my
feeling is something else is up with AD. I mean it can be done, but if
failing, I would look at AD's health before moving forward with any changes
as to what you'er planning. Look at event logs, Sites config, any DCs
multihomed (problematic), replmon for replication status, netdiags, dcdiags,
etc.

Hello David,

Basically you can move the FSMO roles without any problem between the DCs.
Schema just has to be in the forest level, if you have multipl domains or
domain trees in use.

Moving it to implement Exchange is not needed normally, the needed schema
updates for exchange do on the schema master and then install exchange in
the domain. Also make sure that all schema changes are replicated to all
DCs, before installing exchange in the site.

In a single forest domain, like domain.com, without child domains you should
make all DCs Global catalog server.
http://support.microsoft.com/kb/223346/en-us

It is not recommended to install Exchange on domain controllers, use a dedicated
member server for this.

Check replication before hand. Check that replication really works
throughout all domains in the forest.
