Restoring database backup causes errors

I'm trying to restore a database backup from one SpiraTeam environment to another. I followed the instruction mentioned in the Q&A (running SQL scripts and changing the web.config, restoring the attachments directory).

When I try to logon I get this error message (see stacktrace at the bottom):

Exception Details: System.Data.SqlClient.SqlException: Invalid column name 'IS_BUSY'.
Invalid column name 'IS_AWAY'.
Invalid column name 'UNREAD_MESSAGES'.
Invalid column name 'AVATAR_MIME_TYPE'.

My assumption is that the backup file was from another version of SpiraTeam. The Database_Revision value is 400 in the backup I try to restore but 410 in the existing database I'm trying to replace with the backup.

I also tried to run the Update_v4.1.0.3 and the DatabasePatcher.exe to align the restored database with the new version of SpiraTeam but that results in the following error message:

Error occurred during installation - ALTER TABLE ALTER COLUMN failed because column 'ESTIMATE_POINTS' does not exist in table 'TST_REQUIREMENT'.

Does anyone know what I'm doing wrong here?
