Hi Marc,
I always did place the workspaces in the pwa site collection. However,
checking documentation of microsoft recently, they advise differently:
http://technet.microsoft.com/en-us/library/cc197479.aspx
quote:
Create a site collection for project workspaces
We recommend that you create a site collection for your project workspaces
that is different than the site collection used by Office Project Web Access.
Using a separate site collection allows for easier migration should you
decide to move your Project Server installation to a different farm in the
future.
I agree that it is easier migratable, but is having them in the same site
collection not more usable (for eg. search functions ) ?
Are we making it difficult for ourselves if we do not follow MS
recommendations?
