Project Server 2010 - Change Status Manager

Question

End Goal: We would like to perform this change via SQL statement - which I believe I have  I feel like I am missing something and not sure what it is.
Background:  We migrated from a different product to Project Server 2010, while our team members were assisting users to move their projects from the old application to Project 2010 they did not realize their names would appear as status
managers.
The quick solution would be to tell the owners of the projects to change the information themselves (republish or go in themselves and change every line); however we feel this can be cumbersome and too much work due to having hundreds of projects and there
are thousands of fields that need to be modified.  I can quickly accomplish what I want with an UPDATE command and be done with it (no user involvement). 
What I am running into in my test environment is that I can modify the fields (query below) to the appropriate status manager, but I cannot get the changes to appear in Project Professional - it still shows the old value.
I have used the following command to change the Status Manager to the Project Owner (I'm new to SQL, and we no longer have a DBA - so if my code isnt the greatest...I'll fix it)
USE ProjectServer_ReportingUPDATE MSP_EpmTaskSET TaskStatusManagerUID = MSP_EpmProject.ProjectOwnerResourceUIDFROM MSP_EpmProjectWHERE MSP_EpmTask.ProjectUID = MSP_EpmProject.ProjectUID
This modifies all the values correctly - Project Owners become the Status Manager in SQL
Question: Is there something I am missing or can do OR I am not doing to make this new value show up? Is there a better way to do this from an administrative point of view, with no customer/user interaction?
Your help is greatly appreciated
Thank You

Merely my personal opinion having been a Project Server 2010 admin in a medium-sized corporation:
I think you are going to seriously do some damage if you go about trying to modify SQL tables behind Project Server's back. There are a LOT of operations that go into a simple "publish" and I doubt that the minor changes you want to make will account for
all of them. Are you confident you're adjusting all of the values necessary? You may have a detrimental impact on in-flight approvals, timesheets, projects, tasks, assignments.. There is just far too much IMO.
Believe me, I know it is not an ideal solution to have the business make their own adjustments. However sometimes it is just what has to be done. My vote is to craft brief instructions and send them out to the PMs. It's easy to do, they can change one row
and then drag the field down like in Excel to edit all the rest; it's a 1-minute operation, max.
Due to the nature of the field, (not being something you can edit via PWA, and even in Project Pro it only allows you to change it to yourself or another current Status Mgr) I think you'll have a hard time scripting this one via macro etc.. However if you
do find a way, seriously keep in mind your scope and don't edit them all at once, it will need to kick off publishes and check-ins for all the affected projects.
Good luck!
