I'm trying to install a fresh version of DNN into a database with old data; DNN tables and such.

I set an object qualifier for the fresh version so that it would try to use new tables/procedures.

When I loaded the page, it said that there was nothing to upgrade, and stopped. Now I am unable to get DNN installed with the objectqualifer so I can not destroy the old data.

Is there a way to get a fresh version to install in a DB where a previous version was without destroying the previous data?

I have also tried this (on 4.3.5) using an objectqualifier with the same outcome.  I connected to the database via visual studio and found that only the versions table had been created, having the qualifier, and all versions were represented in it.  I performed 'delete from mynew_versions' which left it empty, and browsed again to the site; this time it went thru a full install, creating tables and procs etc with the qualifier.  However i think there must be a bug in the installation because it fell at the last hurdle: could not create a user as one already existed : please register under another name.

it failed to create users and portals, and so when i then tried to access the site, i continue to get the error message, object reference not set to an instance of an object, which i interprete as to do with the lack of users and portals in the mynew_portals and mynew_users tables.

Not sure how to fix this.  Any one else?

2 years later I can answer my own question!

The error about user already exists is due to the file webroot, install\dotnetnuke.install.config containing the instructions for creating the new portal and users, which in dotnetnuke have to be unique across objectqualified versions of the installation - because all installations use aspnet_membership etc which do not distinguish between separate installations.

See http://www.mitchelsellers.com/forums/forumid/2/postid/1429/view/topic.aspx where this is described in detail.

There was also on upgrade to 4.9.1 an omitted {objectqualifier} reference in the dotnetnuke.schema.sqldataprovider script , which caused a failure on setting up a database constraint which because of the missing objectqualifier was pointing at the wrong object.
