Upgrading to SharePoint 2010? Get started by evaluating
- by juanlarios
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

·       SPSReport

·       SPSFarmReport

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!
