Ambiente

Atualização do AEM 6.0 ou 6.1 para 6.3 ou 6.4

Causa

O upgrade do AEM não atualiza a definição do índice automaticamente.

Resolução

  1. Vá para http://aem-host:port/crx/de/index.jsp e efetue logon como o usuário administrador.
  2. Exclua o índice /oak: index/lucene.
  3. Reinicie o AEM.
  4. Monitore os logs para indexação do novo /oak: index/ lucene índice.
Observação:

A indexação não leva muitas horas. No entanto, ela é necessária para o êxito da atualização.
