SCSM Upgrade Tricks: Part 1: Preparation tasks

I will start a series for SCSM upgrade tricks that I faced during SCSM upgrade project I went through in the last 6 months.

 

Today we will start with Preparation tasks". First of all you can check Microsoft TechNet links

1- Upgrade to System Center 2012 – Service Manager

2-Failed Upgrade in System Center 2012 – Service Manager

 

1- Make Sure that Service Manager Servers “Management Server, Data warehouse Server” are updated to Service Manager 2010 SP1 CU4 (Build Number 7.0.6555.131). And make sure

2- Make sure that all Servers OS is running Windows 2008 R2 SP1.

3- Connectors – Please make sure that your connectors are NOT running while you do the upgrade, the upgrade will work, however your connectors will run and attempt to catch up with it. This will in turn, create additional load on the SQL Service on your Management Server, which will in turn affect overall performance and will slow down workflows in particular.

4- Backup all SCSM databases and the SSRS databases “Either using backup Solution or SQL backup”

5- Export and back up unsealed Management Packs since these are the ones which contain customizations and really should be backed up.

a. Create a directory e.g., C:\mpexport that will be the target directory for the export.

b. Load the Service Manager Cmdlet Snapin, so from a PowerShell session type:

c. PS> add-pssnapin SMCmdletSnapin

d. PS> Get-SCSMManagementPack

e. This should show you the list of management packs, then export them to a directory

f. PS> Get-SCSMManagementPack|where-object {! $_.Sealed}|Export-SCSMManagementPack –Directory C:\temp (The use of Where-Object filters the result set to only those management packs which are not sealed).

g. Now back up these management packs.

6- Remove unsupported components for the upgrade like “Microsoft Codeplex Incident SLA Management package”

7- Clients connecting to self-service portal: Clients will need to have Silverlight 4.0 installed and running Internet Explorer 8 or 9. Firefox is not supported as a browser. We need to make sure that all Clients have Silverlight 4.0

7- Remove unnecessary software: As a recommended practice, anything not related to system operation should be removed from servers. Also some of the software on servers may interfere with the upgrade and should be removed like Microsoft SCOM 2007, 2012.

8- Check free space on servers: There should be at least 1 GB free space on server for upgrade.

9- Close management consoles: Management consoles should be closed before starting the upgrade process.

10- Install all perquisites for SCSM 2012

11- Back up your Service Manager and data warehouse encryption keys.

12- Install SQL Server Analysis for data warehouse reporting
