Hi, here you have the general upgrade process http://wiki.alfresco.com/wiki/General_Upgrade_Process
Pay attention to this http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Fconcepts%2Fupgrade-path.html, especially when they say <blockquote>The following diagram shows the upgrade paths for major versions. However, if a direct upgrade to version 4.0 is not successful, an interim step to version 3.3.5 or 3.4.x may be necessary.</blockquote>
To address your needs I think you should fires of all upgrade to 4.0.d and then upgrade to 4.2.c (or 4.2.e)

Rgeards,
Andrea

Hi Andrea;

Thanks for your reply.

I have upgraded Alfresco in the following sequence 3.2.0 -> 3.2r2 -> 3.4.e -> 4.0.e -> 4.2.c.

On upgrading from, 4.0.e to 4.2.c I got an exception: java.lang.ClassCastException: java.util.ArrayList cannot be cast to org.alfresco.service.cmr.repository.ContentData

For that I had ran the query: update alf_node_properties set list_index = -1 where qname_id = (select id from alf_qname where local_name = 'versionEdition');

Does this update query has any impact on upgraded Alfresco server?
