Exchange 2003 - 2010 migration

Hi All,

I'm putting together a plan to migrate from our Exchange 2003 server to a new Exchange 2010 server.  We are planning on also setting up database availability groups for failover.  Can you have a look at my plan and see if makes sense? i.e. is this the correct order to do this in?

Many thanks

1. Prepare the Windows 2008 R2 server                                           

2. Install Exchange 2010 SP1                                                 

3. Add the new digital certificate to the Exchange 2010 server                        

4. ActiveSync configuration                                                

5. DNS configuration and legacy host name settings configuration                              

6. Assign the digital certificate from the new server to the old server                  


7. Change the OAB generation server                                          

8. Convert existing address lists to 2010 format                                    

9. SMTP/Smarthost configuration                                          

10. Moving mailboxes to the Exchange 2010 server                              


11. Moving Public Folders                                          


12. Setting up database availability groups                                    

13. Creating archive mailboxes for users                                          

14. Importing .pst files into archive mailboxes                                    

15. Post installation tasks
Exchange

Hi!

I would recommend you to read the following article:

Thanks but thats not what I asked - I have actually already used that article and others but due to our particular process I have had to come up with my own plan.  I need to know if the order I've described above is the correct way to do this?

What is your particular process that stops you using the many very good guides available already? Perhaps if you explain WHAT your issue is we can help understand the issue better.
Your help has saved me hundreds of hours of internet surfing.

I have posted a list of tasks - all I'm asking is that an Exchange Expert check them over and let me know whether they are ok to be carried out in this order.  

I understand there are ready made guides and I have probably read them all in my preparation for this but unfortunately in the real world there is no 'one size fits all' way of applying an Exchange migration.

Hi Guys,

Looking at the list again, is the changing of the OAB generation server still too high?  ie should I do this after the mailboxes have been moved?
