Do I need a specific Cumulative Update Release (UR) in order to upgrade to SCOM 2012 or 2012 SP1 or 2012 R2?

There is sometimes confusion over upgrades, if you can just upgrade to the next version, or if there is an CU (Cumulative Update) or UR (Update Rollup) minimum level that is required BEFORE a major version upgrade.

The MAJOR VERSION upgrade path is below, which Marnix talked about HERE

This article covers IN PLACE upgrades only, not side by side migrations.

SCOM 2007R2 > SCOM 2012 RTM > SCOM 2012 SP1 > SCOM 2012 R2

No shortcuts… you have to upgrade to each major version before continuing to the next.  So if you are way behind, considering a side-by-side migration can be MUCH less work.  Depends on where you are at.

Ok, back to the Update Rollup requirements.  Technically speaking, the upgrade from SCOM 2007 R2 > SCOM 2012 RTM has a documented CU level.  Per http://technet.microsoft.com/en-us/library/hh476934.aspx which states the following:

Upgrading to System Center 2012 – Operations Manager is supported from Operations Manager 2007 R2 CU4, or from the latest available CU.

Which basically means if you are at CU4 or later on SCOM 2007R2, you can upgrade to SCOM 2012 RTM.  There are no other statements in TechNet which state that any of the SCOM 2012 SP1 or R2 upgrades have a minimum UR requirement. 

Next, the upgrade from 2012 RTM to 2012 SP1 has this page:  http://technet.microsoft.com/en-us/library/jj628203.aspx  This “recommends” updating to SCOM 2012 RTM UR2 (or the latest UR available.)  I cannot say this is a requirement, it is likely what was tested at the time.

Same for SCOM 2012 SP1 to SCOM 2012 R2.  http://technet.microsoft.com/en-us/library/dn521010.aspx  This page states “We recommend that you update all of the System Center 2012 SP1 components with the most current update rollups.”  The most current UR at the time of that publishing was SCOM 2012 SP1 UR4.

Therefore, it appears the “required” upgrade path looks like:

SCOM 2007R2 CU4+ > SCOM 2012 RTM > SCOM 2012 SP1 > SCOM 2012 R2

Our “Recommended” rolling upgrade path looks like the following:

SCOM 2007R2 CU4+ > SCOM 2012 RTM UR2+ > SCOM 2012 SP1 UR4+ > SCOM 2012 R2

If I were performing a rolling upgrade, this is most likely how I’d recommend doing it.  If you are planning a VERY SLOW migration from one version to another, due to lots of additional work that is necessary, such as upgrading OS’s or SQL versions along the way, then you might consider going ahead and applying whatever the most recent Update Rollup available for SCOM 2012.  There are documented here:

http://support.microsoft.com/kb/2906925

One word of caution.  The latest word from the product group just came out, on supported interop scenarios:

http://blogs.technet.com/b/momteam/archive/2014/01/17/system-center-2012-operations-manager-supported-configurations-interop-etc.aspx

They specifically called out one little point:

*Latest CU or UR applies in all cases

This most likely means, this is what they tested, at the time of this posting.  I cant say this is a “requirement”.  If you are doing a rolling upgrade, applying the latest UR to SCOM 2012 RTM before upgrading to SCOM 2012 SP1, then applying the latest UR to SCOM 2012 SP1 before upgrading to SCOM 2012 R2, would be a lot of extra effort, and technically is not a requirement to make the upgrade.   The best decision would be to figure out how long you plan to stay at each stage, how large your management group is, and how much effort it would be in order to deploy the latest UR in each case.  Also to test this in your environment before rolling out the upgrade to production.

The upgrade from 2007R2 CU4+ to SCOM 2012 RTM is the biggest jump, because you must update ALL your agents to SCOM 2012 before finalizing the upgrade.  After that, you can technically leave your agents alone, since a SCOM 2012RTM agent can report to both SCOM 2012 SP1 and R2 management servers.  Then just update your agents at the end, to SCOM 2012 R2 (plus whatever the latest UR is at that time).

There are a TON of really good blogs out there with upgrade experiences, tips and tricks, so I cant possibly list them all.  I did want to point out a really cool link from a colleague, Wei H Lim, who wrote an updated version of the “Upgrade Helper” MP but for moving from SCOM 2012 SP1 > SCOM 2012 R2.  He does some amazing work so if you don’t follow his blog definitely add him to your lists.

  • Hello,
    Quick question, do you know if SCCM 2012 SP1 can 'manage' Windows Server 2012 R2? I guess it would depend on whether or not the SCCM 2012 SP1 client is compatible on Windows Server 2012 R2 operating system.

    Thanks,
    Sven

  • Are Update Rollups Cumulative?
    I am currently at SCOM 2012 SP 1 UR 1. I am wanting to go to R2. Based on your info, I will bring SCOM up to UR 4 for SP 1 before upgrading to R2. Can I upgrade directly from UR 1 to UR 4, or do I need to install UR 2, UR 3, and then UR 4?

  • very good information, thank you

  • @Jacob -

    Yes, you can apply UR4 directly to SCOM 2012 SP1 UR1. The Update Rollups are CUMULATIVE.
