As I’ve previously discussed, at my present client we recently were working very closely with Premier Support to resolve some issues with the cube build. Throughout the course of these discussions, I was told that I really should be running DB Maintenance Plans on the PS07 DBs because with the switch to GUIDs in Project Server 2007, the indices in the various databases can become stale very quickly.

My response to Premier was that since Microsoft has provided no guidance on doing this, and since Microsoft has made such a big deal about not touching any of the databases except Reporting (or Published in very limited circumstances) implementers (including myself) are concerned about doing ANYTHING with regards to Maintenance Plans without guidance from Microsoft.

Premier responded that Chris Fiessinger wrote a blog post about this recently. The agent I was working with gave me advice on how to set up the jobs in the maintenance plan, and promised to press the Product Group to put out some official guidance in the near future.
