Perform the following steps to migrate AEM 5.6.1 to 6.1
Run all maintenance activities:
- Data garbage collection,
- workflow purge,
- version purge,
- consistency check,
- traversal check,
- tarPM optimization.
Make sure there is no error during maintenance activity. This is the KEY.
1. Stop the CQ 5.6.1 instance
2. Archive and delete all log files from logs folder
3. Check repository.xml if any custom login configuration then remove the same (If required)
4. Update the java version to 1.7+
5. Place AEM6.1 quickstart jar parallel to quickstart folder of CQ5.6.x
6. Unpack the quickstart jar by running:
java -jar cq-author-p4561.jar –unpack
Prepare for the migration:
- Run the below command
java -jar cq-author-p4561.jar -v -x crx2oak
The step generates a file crx2oak.properties under crx-quickstart/crx2oak/
Update the logging level for upgrade log to “Debug” mode in the above generated file, then proceeded to next step.
2. Run the jar with the same parameters second time to generate the OSGi configurations needed for the data migration:
java -jar cq-author-p4561.jar -v -x crx2oak
Verify the following configuration files generated to the path crx-quickstart/install
org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.cfg and
org.apache.jackrabbit.oak.plugins.segment.SegmentNodeStoreService.cfg
org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.cfg
path=./crx-quickstart/repository/repository/datastore
minRecordLength=4096
org.apache.jackrabbit.oak.plugins.segment.SegmentNodeStoreService.cfg
customBlobStore=true
Run the migration to CRX3
java -Xmx4096m -XX:MaxPermSize=2048M -jar cq-author-p4561.jar -v -x crx2oak -xargs -- -omigrate
Post migration , monitor Upgrade log and observe for below output which is correct.

make sure to start the upgrade by explicitly using the crx3,crx3tar run modes (
e.g. java -jar aem.jar -r crx3,crx3tar).
As you see last command does output which run mode to use
-r crx3,crx3tar to upgrade in the next step
****************
KEY : Before performing the Final Step - “Performing The AEM Upgrade”
- Delete the 5.6.x standalone jar under crx-quickstart/app/ and set permission to AEM to all
folders, each and every step.
chown –R aem:aem crx-quickstart .
****************
Final Step - “Performing The AEM Upgrade”:
Execute the below command and constantly monitor the error.log and upgrade.log.
Command: java -jar cq-author-p4561.jar -r author,crx3,crx3tar
Most suitable command:
java –Xmx4096m -XX:MaxPermSize=2048M -jar aem-author-p4502.jar -r author,crx3,crx3tar
Verify the error log for “com.adobe.granite.repository.impl.CRX3RepositoryImpl Repository
started.” which clearly showed my repo started as crx3.
