CQ Upgrade issues:

CQ Upgrade issues:

Some time the upgrade of one AEM version to other goes smooth. Other times it may be quite complex. Even though you might have followed all upgrade pre-procedures like clearing custom code, stopping workflows etc, still people face some minor issues.


  • JS will not be loaded so that the comments, or similar buttons gets non clickable.
To get it work we need to refresh Java Script(JS) folders by clearing CQ level cache.

  • Custom usage of deprecated code may stop us from proceeding..
We might have used some deprecated APIs in latest CQ versions like event related(For E.g ProcessJob) or String vs StringArray. We need to re write those classes to get upgrade work with all existing features.

  • Launcher related workflows having issues.
Even though all workflows disabled before upgrade, we may have to redo our workflows to get it work in case of any custom launcher workflows.

  • Personalization not loading after CQ upgrade.

After upgrade some times the personalization does not load. One reason may be Java script does not initialized properly.


To get it work, go to your custom user store,

/apps/ourproject/clientcontext/components/userstore/dialog/items/items/tab1/items/properties/fieldConfig :
property optionsProvider: < refresh this item to get personalization loading(Using a java script refresh or alert)

Personalization Segments folder gets deleted after upgrade. So all created segments may go off after upgrade. So always take backup of segments before upgrade.

In some cases, Client context may go to default with all options enabled, like geo location, browser details, users location request enabled etc. Once done with upgrade you can go and revert it to its previous settings.

  • Product limitations.
There are cases the behavior of AEM for particular feature changes. In such cases we may have to contact Adobe to get a proper resolution. If this is a product issue, Adobe gives patch to help users.
