I tried to update to 4.0 but in several tries I always end up in a failure like this. The first try ended up in "Contraint already exits: Bandana ..." So I did a revert to the old installation. Try #2 and #3 ended in a migration issue too (every time a different one raised).
Is this a known issue? At the moment I cannot find a hint in the documentation.

There is a known issue for SQL Server that causes upgrades to fail due to some exisitng database constraints. The bug is outlined here:
The provided SQL queries in the workaround should allow you to complete your upgrade:
alter table CONTENT_PERM drop constraint cp_unique_user; alter table CONTENT_PERM drop constraint cp_unique_group;
Since your upgrade failed, you'll still need to roll back to your backup before running the queries.
We're running into the same Problem upgrading from 3.5.9. After the first failure we thought it might be a good idea to upgrade to 3.5.13 first an then going to 4.0. But the error allready occures when trying to upgrade from 3.5.9 to 3.5.13.
I can post the full log if it helps as there are some more errors in the eventlog
I had this bandana problems too.
What solved my problem is:
1. Do an upgrade from 3.5.7 to 3.5.9
2. Run the SQLs
alter table CONTENT_PERM drop constraint cp_unique_user; alter table CONTENT_PERM drop constraint cp_unique_group; alter table CONTENT_PERM_SET drop constraint cps_unique_type;
3. Do the upgrade to 4.0
