umalik712 -> upgradation from exchange 2007 to 2010 (5.Aug.2011 2:11:28 AM)

Hi,
We are using exchange 2007 sp2 on windows server 2008 x64 standard, we are all set to upgrade to exchange 2010. But we have new hardware with new os (Win server 2008 R2 x64 enterprise) installed. We donít want to change our owa link and domain name. Because we have many users using owa link only not outlook. Please suggest me how to install new server with same name and domain, how we can move the exchange data in new server. Both servers having 1 TB single HDD. Existing edb size is 300 GB and 200 GB respectively. Only way we can understand that export pst from edb file and import in new server. But will increase our downtime and efforts. Can we try making new server as ADC in same domain then install exchange 2010 on it ? I have tried this steps on 2003 server 2 years back, it has make 2nd server as replica of existing server AD. But in current case we have exchange server installed on old server and latest version required on new server with old database.
Please suggest the best way to configure new server with no link change and database will remain same.


Thanks

First thing you got to understand is, you can;t have the same server name.
You don;t have to change your OWA URL. You can keep the same.
Best way is Migration and its a proper way.

Please help me out. how to make smoothly working in exchange 2010, I have forefront for exchange and Symantec endpoint protection as antivirus. I have one fortinet firewall on gateway.

Hi,
We have transferred all FSMO roles to new server and shut down ols one. but service of exchange has not started on new 2010 server. Then we tried to revert back all roles to old server but scheema & domain name is not moved, If we continue with current scenario both mail servers are not working, please help me out. I have searched on some sites there is DNS problem. Checked all things but nothing found incorrect but dcdiag on (new server) given error :  Starting test: LocatorCheck
        Warning: DcGetDcName(GC_SERVER_REQUIRED) call failed, error 1355
        A Global Catalog Server could not be located - All GC's are down.
        ......................... mail.com failed test LocatorCheck
     Starting test: Intersite

Waiting for valuable reply,
I can provide the full text file of dcdiag log.

Thanks
Umesh

Hi,
Depending on how you have 2007 setup today you might be able to break the CCR cluster (leave SCR going if you have that), rebuild that node as 2010, move the mailboxes, then rebuild the other machines. It'll require calculated time where you're running on a single node, but it gets around having to buy a ton more servers. This of course does not take care of the CAS/HUB issue, but those should be easier.Thanks.
