Upgrade Path

Direct Upgrade from 10.2.0.5 or 11.1.0.0 Grid Control

Out of place upgrade

Upgrades from previous Upg ades o p e ousreleases, determined by your base release

Example, Windows 32 bit platforms you can upgrade from 10 1 0 x 0 toyou can upgrade from 10.1.0.x.0 to 10.2.0.2, bypassing the 10.2.0.1 installation

Refer to Certification MatrixRefer to Certification Matrix available in My Oracle Support

*Old versions of agents will not work with 12.1 OMS

Upgrade Requirements

• Older versions of agent (< 12c) will not work with 12c OMS The OMS upgrade will happen prior to Agent upgrade• The OMS upgrade will happen prior to Agent upgrade

• 12c OMS can be on same/different Host • Minimum 12c Infrastructure requirementMinimum 12c Infrastructure requirement

Upgrade Approaches

Complete Cutover With Higher Downtime (Using One System)*• EM OMS and all agents are upgraded at the same time, with some

downtimedowntime• Both pre-12.1 and 12.1 installations co-exist and only one of them can be

active at any given point in time• Entire system (agents, OMS, Repository) gets upgraded to 12.1

i lt lsimultaneously

Phased Cutover With Minimal Downtime (Using Two Systems)*• Upgrade can be staggered over time, but this incurs minimal monitoring

downtime• Both pre-12.1 and 12.1 systems co-exist and can be active simultaneously

until all targets from ‘pre-12.1’ are migrated to 12.1 system in an orderlyuntil all targets from pre 12.1 are migrated to 12.1 system in an orderly fashion.

• 12.1 system will only contain12.1 agents/targets

* Henceforward referred to as One-system and Two-system approaches respectively Henceforward referred to as One system and Two system approaches, respectively

How to apply the Upgrade Console Patch

Prereq for applying the patch:i. Opatch version for applying the upgrade patch 10205 should be 10.2.0.5 .Opatch

number : 6880880 to download it from ARUnumber : 6880880 to download it from ARUii. Opatch version for applying the upgrade patch 11101 should be 11.1.0.8.4

Opatch number : 6880880 to download it from ARUiii. if the opatch present in 10.2.0.5 or 11.1.0.1 OMS home is lesser that above

ti d t h i l it ith t hmentioned opatch version replace it with proper opatch

Set the Environment variables:

How to apply the Upgrade Console Patch-1Patch application steps

1. Copy the upgrade console patch to the OMS machine and unzip the upgrade console patch2. Cd to unzipped location 3. Refer to the Readme for applying the patch and it will be present in unzipped location. Follow

the Readme religiously ☺4 Stop the OMS4. Stop the OMS5. Apply the patch

How to apply the Upgrade Console Patch-2Patch application steps

1. Copy the upgrade console patch to the OMS machine and unzip the upgrade console patch2. Cd to unzipped location 3. Refer to the Readme for applying the patch and it will be present in unzipped location. Follow

the Readme religiously ☺4 Stop the OMS4. Stop the OMS5. Apply the patch

How to apply the Upgrade Console Patch-3Post Patch application steps:

If you don't execute Post patch application steps then you will get the pre- upgrade console link in the GC but while clicking on that link you will get an Internal error

1.Login to database as sys user:Run $ORACLE_HOME/sysman/preupgc/puc_dblink_pkgdef.sqlRun $ORACLE_HOME/sysman/preupgc/puc_dblink_pkgbody.sql

2- Systems Approach – how to restore old system?

1. You will have your old GC system intact We don't touch your oldintact. We don t touch your old OMS.

2. We don't touch your repository and it will be up and runningp g

3. You have to manually start your old agent

4. You have your old GC back ☺

Enterprise Manager 12.1 – Post Upgrade StepsSteps

Post Upgrade Console (from 12.1 Grid Control)Deferred data migration

• Lazy migration of historical data• Status tracking from post upgrade console • Ability to retry

Accrued target data migration• Applicable for two-system approach only• Automatic migration of accrued data from old system to 12C

Diff reports• Configuration or setup-related changes that were manually made to the g p g y

old system while 2-system upgrade was happening Deleting Old Agents from repository
