Exchange Server 2003 to Exchange Server 2010

I am trying to transition from Exchange 2003 to Exchange 2010SP1. The base server is Windows server 2008 R2
During the installation I had a failure at the installation of the mailbox role. After spending a week to resolve this issue,including following suggestions on this site, I decided to roll back and start from scratch using the Exch. 2010 media without SP1. Unfortunately I am now running into issues while trying to remove the routing group connector.
When running the command in EMS, I am getting the following:

[PS] C:\Windows\system32>Remove-RoutingGroupConnector -Identity "Exchange Administrative Group (FYDIBOHF23SPDLT)\Exchang
e Routing Group (DWBGZMFD01QNBJR)\RWLE2k3-RWLE2K10.lyall.com RGC" -DomainController RWLCADC02.LYALL.COM
The operation couldn't be performed because object 'Exchange Administrative Group (FYDIBOHF23SPDLT)\Exchange Routing Gr
oup (DWBGZMFD01QNBJR)\RWLE2k3-RWLE2K10.lyall.com RGC' couldn't be found on 'RWLCADC02.lyall.com'.

Ok, so the cmndlet ran without error. Now when I proceed with uninstalling Exchange 2010, I get the following error under the mailbox roel section during uninstallation

try this :
Solution 1 :
Disable-Mailbox -Arbitration "System*" -DisableLastArbitrationMailboxAllowed


Disable-Mailbox -Arbitration "Fede*" -DisableLastArbitrationMailboxAllowed


solution 2 :

1-Delete the Discovery Search Mailbox, and remove the account from AD. In my case it was “DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}”, the GUID on your setup will be different.
2-Remove the “action” and “Watermark” registry keys from:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14\MailboxRole
Otherwise you may receive a “BuildToBuildUpgrade” error when you try attempt the next step.

3-Prepare active directory for Exchange to re-create a new Discovery Search Mailbox:
setup.com /preparead
4-Run Setup again and it should work without issue.

with good luck to you :)

I would like to thank all of you for the expert assistance provided.
As it turned out, the Exchange Site replication service on the Exchange 2003 server was dissabled. I enabled it and started it. I then restarted the uninstall process on the 2010 box. This time round, exchange 2010 uninstalled cleanly. I checked on the 2003 box and the routing group connector  had been removed also.
Now I need to start the installation again ,only this time I am not going to use the media with SP1.I will install Exchange 2010 and then apply the service packs. Do I need to do anything to the environment to restart the installation?

I have seen this post and tried the solution, but it did not help. The problem is that it is a Windows Server 2008 R2 box and the admin share is not working.
0
dipamAuthor Commented:
The issue is that in Server 2008 R2 the admin share is not enabled, yet the Mailbox role installation script calls it. I have tried everything to enable it, but am not having much success.
0
dipamAuthor Commented:
This issue had caused me great headaches. In the end, the original issue turned out to be the fact that the admin share on Windows Server 2008 R2 is dissabled by default and the mailbox role installation script uses a unc path with c$.
As I had messed around with the install a lot during troubleshooting various issues, I decided to start from scratch.
I am pleased to anounce that yesterday I re installed Windows, then enabled the admin share and Exchange installation fos flawless.
