You can use back up and restore which works best with an external hard drive.
On the Vista machine launch the PSE7 Organizer and on the menu click:
File >> Backup Catalog to CD, DVD or Hard Drive
On the laptop launch the PSE11 Organizer and click:
File >>Restore Catalog
Then navigate to the TLY file within the backup folder after connecting your hard drive.
See this link for further details on the backup and restore procedure.
It is recommended to repair/optimize the catalog (File >> Catalogs), reconnect all missing files (file>> Reconnect>> All Missing Files), and delete the still missing ones before going for a backup.
