AEM instance can be upgraded to 6.4 version in two ways.
- New AEM 6.4 setup
- In-place upgrade
Let's c In-place upgrade process.
In-place upgradation Process:
- Start you AEM 6.2 instance.
- Check all consoles are working fine.
- Remove all custom code and configs.
- Check “quickstart.properties” file is present under
/crx-quickstart/conf . If not, copy from other instance and paste it in above location. - Run offline compaction to reduce repository size. Check how to run offline compaction.
- Goto packageshare and download the package
pre-upgrade-package-cq62-1.2.zip
- Navigate to package manager and install the
pre-upgrade-package-cq62-1.2.zip
- Once package is installed, navigate to OSGI Config Manager. Search for "preupgrade". Look for com.adobe.aem.upgrade.prechecks.mbean.impl.PreUpgradeTasksMBeanImpl.
Lets see what these are parameters do:
VersionPurge: This can be used to purge page versions.
GenerateBundlesListFileTask: List of bundles will be checked and placed in some path. This path can be found in your log.
DisableReplication: Disable replication agents
WorkflowPurgeTask: Purge workflow. I not used while performing upgrade as I don’t have any workflow purge settings.
com.day.cq.audit.impl.AuditLogMaintenanceTask: Audit log in logger.

Hi,In step #3 what exactly means by remove all custom code and configs?
ReplyDeletePlease see my reply
Deletecan you please explain more about step 3. Thanks!

DeleteIt Means your repository should not have any of your client/project code in apps folder. i.e no JSP/HTL files config files and your Jars should be present in your apps folder other than the ones that are present by default.
ReplyDeletei.e your AEM 6.2 instance should have only images and pages. After content is migrated to AEM 6.4 you need to make some changes in your pom files of your project eg change uber jar version and perform fresh maven build into the new upgraded AEM 6.4 instance..
hey Oliver, thanks for your response, do we also need to remove all the custom components that we built under apps/myProject folder . if that is the case, how about the pages referring those components will not throw errors? while doing upgrade.
DeleteMany Thanks..
Hello when trying to do a repo migration, getting below error. Can you let me know how to fix it?
