Hi, hope someone can help me out here.
Old server running Windows 2003 and Exchange 2003 (all latest service packs etc)
New server running Windows 2008 and Exchange 2007
I was following this ( http://www.msexchange.org/tutorials/Transitioning-Exchange-2000-2003-Exchange-Server-2007-Part1.html
)guide on transitioning the exchange from the old server to the new one.
All was going well until I got to part 3, repilcating public folders. To let you understand we have about 40gigs of data in public folders. I know this is not good but its out with my control.
I kicked off the replication of these folders from the old server to the new server.
I also started moving a few of the mailboxes over. All at this point seemed OK.
The next day I had the client phone me saying that email was running dead slow, and could I fix it. I did the typical reboot the 2 mail server and while this kicked out some of the messages that were in the queues it didn't improve much.
I decided to undo the replication so that all replicas would be on the old server again. Oddly when I checked the size of the public folder store on the new server it hadn't grown at all and users on the new server couldn't see any data in these folders.
I also had the problem that those on the new server could only email each other and likewise with the old server, there seemed to be no routing between the server working at all. I thought this might be due to overload from replication.
Eventually I've ended up moving the mailboxes back to the old server. This solves them being able to send and receive email but the speed issue is still there. Its like the old server is just constantly trying to do something that's slowing everything on it down.
If I look on the ESM 2003 manager at the queues you can see that there are thousands of messages. The number just keeps on going up until I reboot, then its just starts again.
I'm now trying to get to the stage where I want to uninstall the Exchange 2007 server for now without causing issues on the old one.
The uninstaller fails on 2 points.
1. Public folder contains replica's. I have tried everything and I cannot see any replicas of the public folders. There is only 5 or 6 system folders in there.
2. Routing group connectors. I can see using get-routinggroupconnector that there are indeed 2 connectors, one going to the other server the other coming back.
What I need to know is, can I safely (ie without loosing any data from the old server) use ADSIedit to remove the public folder store from the new server and, can I delete the 2 connectors?
Basically, will this fix this problem for me and my client?
I am desperate to get this sorted out for 9am on Monday so any help would be very, very much appreciated.
Thanks in advance.
