Upgrade from 8.1 to 12v5 - Any Problems?

Discussion created by ca.portal.admin on Apr 5, 2010
All, we are contemplating the upgrade from Clarity 8.1 to Clarity v12 r5. We have a heavily customized Clarity, including:  - Hundreds of fields created in many objects such as Project, Idea, Change Request, etc.;- Lots of new Objects created, many of them childs from the Project Object;- Hundreds of Views, which differ according to some partitions we created;- Lots of Processes and Jobs;- Lots of Portlets, some using out-of-the-box or custom Objects, and some using NSQL queries.  I was wondering if any of you performed an upgrade with a similarly customized Clarity, to see if the upgrade has some trouble or if it works fine. Any experience you could share will be greatly appreciated.  Thanks in advance.  Eugenio
