Migrate EV11 to new Exchange org name

Hello

I have a requirement to change the organization name of our Exchange environment to a new name (Don't ask why !!!)

We have EV11 for Exchange installed and was wondering if i ran through the following process what the ramifications on EV would be?

1. 0 Day archive all mail in mailboxes to EV

2. Uninstall Exchange ORG in forest

3. Re-install exchange with NEW ORG name

4. Create new Exchange mailboxes for users now in NEW Exchange ORG.

5. Re-attach EV to new Exchange ORG

6. Re-attach Archives to NEW mailboxes

7. Re-create stubs in mailbox for archived content from OLD ORG name.

Thanks

Paul
