P12 Migration: Sharepoint sites migration issue

[Jesse]

Posting to Sharepoint group and Project Server group.....

Sharepoint workspace sites in P11 environment exist as “top-level†site
(http://<P11 Environment>/sites/projectserver_xxx) and get migrated as
“top-level†site in P12 environment (http://<P12
Environment>/sites/projectserver_xxx).

However, the new workspaces that are created in P12 environment appear to
have been created as a site inherited from PWA (http://<P12
Environment>/PWA/ProjectName_Published).

The issue that we are seeing is that some of the webparts that are available
in P12 environment (http://<P12 Environment>/PWA/ProjectName_Published) are
not available on the sites in P12 environment migrated from P11 environment
(http://<P12 Environment>/sites/projectserver_xxx), as seen in the image
below,

We attempted the following things to fix the above issue,

1. Get P11 migrated site restored under PWA area using STSADM – this didn’t
work as this works only for “top-level†sites and restoring a site under PWA,
which is another “top-level†site didn’t work. Backup and Restore operations
work only for “top-level†site to “top-level†site.

2. Export web part from PWA area to migrated sites – ran into some Access
Denied issue

So we're thinking that we'll have to create each workspace for each project
(http://<P12 Environment>/PWA/ProjectName_Published) then manually migrate
(copy n paste) from old to new.

How we can get these missing web parts made available on the migrated sites
-- more move existing sites to under PWA (http://<P12
Environment>/PWA/ProjectName_Published)
