CAUTION
AEM 6.4 has reached the end of extended support and this documentation is no longer updated. For further details, see our technical support periods. Find the supported versions here.

Depending on each site’s topology and features, the following actions may be necessary when upgrading to AEM Communities 6.4 or installing the latest feature pack.

This section is specific to Communities and supplements the information provided in Upgrading to AEM 6.4 (platform).

Upgrading from AEM 6.1 or Later

Reindex Solr

When installing a new Communities feature pack on a deployment configured with MSRP, it will be necessary to:

  1. Install the latest feature pack

  2. Install the latest Solr config files

  3. Reindex MSRP

    see section MSRP Reindex Tool

Enablement 2.0

As of AEM 6.3, the enablement features no longer store reporting information in MySQL. The MySQL dependency is only there for tracking SCORM content.

Please contact customer care for assistance in migrating content from Enablement 1.0.

Upgrading from AEM 6.0

If pre-existing UGC needs to be retained, then the means to do so depends on whether the deployment stored UGC on-premise or in the Adobe cloud.

Adobe Cloud Storage

If the upgraded site was configured to use Adobe cloud storage, then it may appear (incorrectly) as if all UGC has been lost as the SRP methods will be unable to locate the pre-existing UGC in the old location.

Thus, there is the ability to instruct ASRP to use AEM 6.0 compatability-mode to access UGC.

For all AEM 6.3 author and publish instances:

  1. Sign in with administrator privileges and configure ASRP.

  2. Follow these steps to make the existing UGC visible:

    i. Browse to the web console. The default URL is
    https://localhost:4502/system/console/configMgr.

    ii. Locate AEM Communities Utilities configuration and select to expand the configuration panel.

    iii. Uncheck Cloud Storage and click Save.

On-premise Storage

If the upgraded site did not use cloud storage, any pre-existing UGC must be converted to conform to the new structure introduced in AEM 6.1 Communities in support of the common store.

For this purpose, an open source migration tool is available on GitHub:
