How to Upgrade an EPiServer CMS 5 Site to CMS 6

The EPiServer Deployment Center can be used to upgrade an EPiServer CMS 5 R2 SP2 site to CMS 6.  The upgrade process is quite simple and converts the site content, settings, and form data, in place, from the old format to the new.  The upgrade process upgrades the EPiServer user interface, assemblies, and converts database objects and data as needed. 

If you have multiple sites, each site can be upgraded one at a time as long as they are in separate CMS instances / databases.  If you are running an enterprise configuration where multiple sites are managed from the same CMS instance / database, all of the sites will be upgraded at the same time.

The EPiServer Deployment Center will take care of upgrading the content and the EPiServer components, but it is strongly recommended that you thoroughly test your Page Templates, Dynamic Content, Plug-ins, and any other modules that reference the EPiServer API or web services to ensure that there are no compatibility issues with the latest version.

For more details on what the upgrade process does, check out Per Bjurström’s blog entry, Upgrading to CMS 6 RC1.

Hi,

In Step 7 I get an this error on the Database Settings:
Database Name : Error {Namespace prefix 'epi' is not defined.}
Database Server Name : Error {Namespace prefix 'epi' is not defined.}

Does anybody got an idea what the error is trying to tell me?

Thanks!

Will this work with a "EPiServer CMS 5 SP3" site too?

I also get the Database Name : Error {Namespace prefix 'epi' is not defined.} error, does anyone know how to resolve it? Mark, did you get around it somehow?

I had an error in my web.config, so the site wouldn't start. So I guess the "Database Name : Error {Namespace prefix 'epi' is not defined.}" error message is trying to tell me that I need to check that the original site is working before I expect the upgrade process to work.
