I recently spoke at Tech Days 2010 in Winnipeg. These are some tools that will I showcased to help you evaluate where you are now.

 

·       PreUpgradeCheck

·       SharePoint BPA

o   http://www.microsoft.com/downloads/en/details.aspx?familyid=cb944b27-9d6b-4a1f-b3e1-778efda07df8&displaylang=en

·       SPSReport

o   http://spsreport.codeplex.com/

·       SPSFarmReport

o   http://spsfarmreport.codeplex.com/

I also showed a Solution Downloader found here: http://spsolutiondownloader.codeplex.com/

I also wanted to give you some useful Power Shell commands to work with visual upgrade:

Find out Which UI Version a site is at:

  $sc = Get-SPSite <URL>; $sc.GetVisualReport() | Format-Table

Upgrade UI for an entire WebApp:

  $webapp = Get-SPWebApplication <URL>

  foreach ($s in $webapp.sites)

  {$s.VisualUpgradeWebs() }

Upgrade UI for a single-site:

  $site = Get-SPSite <URL>

  $site.VisualUpgradeWebs()

Revert UI for single site:

  Get-SPSite <URL> | Get-SPWeb "webname" | Foreach{$_.UIVersionConfigurationEnabled=1;$_.UIVersion=3;$_.Update();}

Revert UI for all sites:

  Get-SPSite <URL> | Foreach{$_. UIVersionConfigurationEnabled=1;$_.UIVersion=3;$_.Update();}

 

 

Hope it helps you out!
