Hello, I am new to SCOM, we are planning to upgrade our SCOM from SP1 to R2. Below are the details about our SCOM environment. <> Clustered RMS (Windows Server 2003 Enterprise x64 Edition Service Pack2) <> Clustered DB server (with OperationsmanagerDB and DatawarehouseDBin it) (Windows Server 2003 Enterprise x64 Edition Service Pack2) <> 1 Management Server (It is located in other region and this server is our SCOM's log shipping server & Reporting server) (Windows Server 2003 Enterprise x64 Edition Service Pack2) <> Around 260 agents reporting to RMS Now we are planning to upgrade the RMS server, DB server OS to 2008 and SCOM DBs to 2008 from 2005. I am not sure how to plan the upgrade i.e. which upgrade should be done first? OS, DB or SCOM. Kindly help by suggesting the best plan and documents to go through to complete the upgrade successfully. Thanks for your help. Regards, Santhosh

Hi Personally, I'd do the upgrade to SCOM 2007 R2 first. This is fully documented: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=19bd0eb5-7ca0-41be-8c0f-2d95fe7ec636&displaylang=en http://blogs.technet.com/b/kevinholman/archive/2009/05/23/my-experience-upgrading-to-opsmgr-r2-rtm.aspx Once this is done, then plan the other migrations.

Hello Graham, Thanks a lot for the reply. After the SCOM upgrade to R2 and some days wait to verify it, shall we upgrade the OS or DB? Thanks, Santhosh

Hi Santosh Personally, I'd probably do the OS first and then the database - but I don't think there is an issue either way around as both SQL 2005 (sp1 \ sp2 sp3) and 2008 (sp1 \ sp2) are supported on both windows 2003 and windows 2008. http://technet.microsoft.com/en-us/library/dd789004.aspx http://support.microsoft.com/kb/974722 As I mentioned on the other thread - I'd look to do all of this slowly. Plan for it to take a month and really make sure the system works after each phase. Cheers GrahamView OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/

Greetings, I have 3 more questions The Downtime of the monitoring while upgrading the SCOM, will be while upgrading RMS, MS & Agent but the data loss will be only during Agent upgrade. Am I right? Can we upgrade SCOM SP1 to R2 in the below way? 1. Promote a MS to RMS 2. Decommission the old RMS 3. Build new windows 2008 server, install SCOM R2 in it use the existing DB 4. Upgrade the SQL & DB Server Or Inplace upgrade is the only option for SCOM? Thanks Santhosh
