Joel Oleson's Blog - SharePoint Land : Don't be afraid of Prescan - Part 1: http://blogs.msdn.com/joelo/archive/2007/04/13/don-t-be-afraid-of-prescan-part-1.aspx
Example of good PreScan results:
07/19/2006 17:17:01 Scan finished without failure. 07/19/2006 17:17:01 Number of sites skipped (already scanned): 0 07/19/2006 17:17:01 Number of sites scanned: 100 07/19/2006 17:17:01 Number of broken sites: 0 07/19/2006 17:17:01 Number of webs scanned: 138 07/19/2006 17:17:01 Number of broken webs: 0 07/19/2006 17:17:01 Number of webs using custom template: 0 07/19/2006 17:17:01 Number of pages scanned: 0 07/19/2006 17:17:01 Number of unghosted pages: 63
Per quanto riguarda le unghosted pages vi invito a leggere l’articolo seguente che dovrebbe chiarirvi ogni possibile dubbio:
Bill Baer : Ghosts in the Machine?: http://blogs.technet.com/wbaer/archive/2007/08/10/ghosts-in-the-machine.aspx Innanzitutto un chiarimento doveroso: "In most cases an unghosted page is the result of customization through Microsoft FrontPage and/or Microsoft Office SharePoint Designer 2007"
Ghosted Pages and Upgrade
"Ghosted pages, though, in many cases can be upgraded safely depending on the extent of their customization (see introduction for caveats) should be considered for reghosting at the time they are upgraded. The gradual upgrade approach allows administrators to reghost (reset to site definition) pages during the upgrade process and enables the reghosting of pages at a more granular level. Reghosting in a gradual approach can be applied through the Upgrade user interface or optionally using the STSADM -o command line argument -Reghost in the upgrade operation, for example STSADM -o upgrade -sidebyside -url http://www.contoso.com -sitelistpath <pathtoxml> -reghost. This granularity allows you to decide where you would like to reghost and what customizations should be retained during the upgrade. The database migration approach and inplace approaches both permit the upgrade of unghosted pages preserving the customizations; however, these pages will be upgraded in their existing state and will need to be reghosted post-upgrade to enable Microsoft Office SharePoint Server 2007 functionality.
