I have a general query regarding the database used for configuring/setting up ALM 11 (Quality Center). I have upgraded to ALM 11 from QC 9.0 before (via QC 9.2)and I faced some issues regarding SQL collation of the database (_db files) and model database (used by QC to create database).

Is there a defined pre-requisite regarding the SQL collation of the database used for ALM 11.00?

Please share your experiences.
