I'm a beginner in SharePoint so forgive me if the question is too simple.
I've been given a task to revamp an existing SharePoint portal. I will basically focus on the visual branding and also on improving some of the services. The problem is the existing code is a big mess and it was handled by two or three companies before and no documentation whatsoever. Moreover, the upgrade process from SP2007 to SP2010 was not properly done.
Personally, I don't want to waste time figuring out errors in undocumented code. So I advised the client to start with a clean install and build the complete layout from scratch. They insisted that they want to keep their existing data ( structure + content ) and web parts. Plus we have some time limitations.
Based on your experiences, could you please suggest an approach that might help in a similar situation? Is there a way to start clean portal with new layout but at the same time keep the data?
I appreciate your help.
