Good afternoon Paul,

I will start this migration too and I would like to know what was your experience with this.

I´m taking the technote http://seer.entsupport.symantec.com/docs/285651.htm as experience, but it refers about Exchange 2003 migration.
 

Is any other step as you took?

Best Regards,
 
Felipe Bender

Thanks Amit.

Felipe ill let you know how i go on

Hi

I will borrow your topic...

After succesful migration from Exchange2003 to Exchange 2007 (basicly there wouldn't be any problems since we are still in same site, Ad...) what is the exact procedure to remove old Exchange 2003 from EV SITE?

Well,

Migration is now complete everything went smoothly apart from a few permission issues on the new exchange server. EV made the migration especially the time consuming part of malbox migration a doddle.

i removed the old exchange server from ev by removing the achive task and then removing the target.

all seems to be ok.

Hi Amit, With regards of upgrading exchange 2k3 to 2k7. We are using EV 7 sp5 and using exchange in resource forest. We are moving exchange server form the one org/domain to the org/domain where EV server located and therefore ExchangeLegacyDN will change. I would appreciate if you suggest or advise the procedure of this type of migration where users will be able to access their archive items from the new mailbox?

My main worry is that how to relink the current archive store to the moved mailboxes. 

Can you please verify my below migration action plan: 

Disable usersMove user mailboxes to new exchange server.

Provision new exchange server as traget and task.

Synch the new exchange server with EV.

Delete EVDefaultID for old archive accounts on the Exchange sql tableEnable new users and use.

Select Archive to re-link it with the old store. Thank you Hawry

See the following technote about the registry key syncinmigrationmode which will answer your query about relinking mailboxes to archives:-
