Migrating to Exchange server 2010, if you have multiple sites in AD do you need a hub transport server at each site?
We are migrating to exchange server 2010. We have multiple sites in our active directory sites and services. Some of the site are just a handful of users but have a domain controller at the site. Do you need to install a hub Transport server at each site?
no you should not,
installing a CAS without mailbox server is useless, the whole word is going towards consolidation so get 2 good datacenters and build a HA solutions and let all your users connect to these.

I assumed they would be having mailbox servers at the site since there was no mention of them in the question.
You only need to have a Hub Transport Server in each site that has a Mailbox Server Role installed in that site.
demas,
Depending on the number of users and amount of bandwidth available between the sites, your smaller sites can connect to a main site for their mail with no exchange services installed locally.
If I were able to do my migration here over again, I would setup a DAG between my larger sites, so that Site A is replicating to Site B and vice versa for redunancy and availability.
For the smaller sites though, I just setup my users to run in cached mode and connect to the exchange server here over our WAN.

There is no mention of mailbox placement so I assumed a mailbox server was in location at the remote site, which is why I suggested what I did.
If there is no mailbox server at the remote location then there is no need for a HT or CAS role to be there.

Sorry just to be clear:
We have a datacentre which would host the mailbox server and the client access server and have a centralised Hub transport server. We have 4 Sites none would have a mailbox server. Im under the impression Exchange 2010 handles its routing through Active directory sites and services, hence why im unsure if a hub transport server should be placed on each site. One site has a fast link, the other 3 sites have ok ish links.
Thanks
