If you have an M3 Business Engine database that you want to attach to your environment, you must first attach a database middleware to the node hosting the database. Then the task Attach M3 BE Database can be run on this node. This method can be useful when upgrading from an older M3 Business Engine version, or if you want to attach a backup of a database to your environment.
New database schemas for M3 BE must be owned by the user M3SRVADM. If there are schemas to be used that are now owned by MSRVADM, you must change authority for the database.
