Umbraco-CMS: v8.1 migration from v7 results in an error due to a unique index on cmsContent

We’ve seen a database migration from v7 to v8.1 fail due to the presence of an index named IX_cmsContent. This index might be linked to other tables that make it fail.

Need to investigate (this was reported by @marcemarc ).

It’s slightly hard to to test this because if you are using a dacpac you have to manually populate all of the basic data required to run which is a fair few tables. I’ll see if i can post a nightly build to here to see if @robertjf , @rgdagostino or anyone else can test, stay tuned.

@rgdagostino Glad to see some progress! You might have a lot of data to migrate, I ran into a similar issue with a large database, try to fiddle with the timeouts in web.config: https://github.com/umbraco/Umbraco-CMS/issues/5803
