Changing Exchange 5.5 Organzation 2

[rswift]

We are a red headed step child state agency. We are being moved under a new state agency from our current one. We will have to change the Exchange Organization. What is the "Best Practice" for doing this?

If anyone calls and says "I know a little something about computers" just tell them to reformat it.

Hmm, that's not the whole story. You can change the Display name of the organization quite easily within Admin - the underlying directory name does't change, but you hardly ever see that. If you have multiple sites, you need to connect to a server in each site to effect the change.

Alternatively, instead of reinstalling Exchange, you can use Move Server Wizard to move each server to a new org. Okay, it's probably as desruptive in the long run as reinstalling Exchange, but it has different advantages and at least it is another option available to you.

You have 2 options that you can choose from depending on the number of users you have.

1. Move server wizard - I have used tyhis successfully on servers with about 300 mailbox and works fine.

2. use exmerge to take the messages into pst files if you have few mailboxes and move them to teh new site and add their old x500 addresses so that old messages dont get bounced back if replied.

X.500 address redirection will only work within an Exchange Organization - this request is speciically about moving to a different Organization.

lets assume we have company A.com and B.com, you want to move company B into org A. change the MX records for company B pointing to the mail gateways in company A, set company A to accept messages for the domain B.com.

now is you had the old x500 addresses from the old org, exchange should be able to resolve and deliever the messages to the mailboxes in the new org.

Iam pretty sure that would work.

X.500 resolution is internal to the Directory within the Exchange Organisation, it's totally seperate from the MX records (which reply on a totally different routing mechanism).

you might be correct, i havent tested this accross orgs, but have tested this internally - but what you have said makes sense.

Apologies for those who I have now managed to confuse. But we all learn something new here.
