Exchange migration 2003 to 2010, what do I do to Vault?

Hi,

So for years we have had an Exchange 2003 environment, with 3 Virtual servers in a cluster.

We have Vault 10 pointing at this and everything was fine. E-mail archiving is happening on the mailboxes and all is well.

We have now almost finished Exchange mailbox migrations to new Exchange 2010 servers on the same domain.

My question is this.

1) How do I add the new 2010 servers, so the users will start archiving off again?

2) How do I safely remove the old 2003 server from Vault, as they will be switched off in a couple of weeks.

Any guidance you can provide would be very welcome.

Thanks

James
