migrating exchange users

Hi there,

my company has taken over another firm and that firm need to use their current emails. We have decided to add the domain to out exchange server and create the same email addresses. I am going to do the physical move of the users to our network domain and possible the users will be given new laptops. I just need to do things neatly and I need some advice from experts if I need to do anything on the current exchange server and what steps shall i follow to move the users current mailbox, archives, calender, sent items and so on.

Thanks,
LVL 5

Here is process that I went through during cross migration, we did migration:

1. Create DNS forwarding on both forest. The result shall be DNS at target forest able to ping DNS at source forest and via versa.
2. Create a forest trust relantionship between source and target forest. http://technet.microsoft.com/en-us/library/cc816810(v=ws.10).aspx
3. Install ADMT/Password Export services on target forest. http://technet.microsoft.com/en-us/library/cc974435(v=ws.10).aspx
4. Using ADMT/Password Export services, migrate the AD Users/Groups from source to target forest.
5. Migrate the mailbox from source Exchange organization to target Exchange organization. E.g Move-Mailbox, http://technet.microsoft.com/en-us/library/aa997145(v=exchg.80).aspx

Here is a few issue, that we are facing after migration:
