Microsoft this week have released an update for the SBS 2011 Migration tool that ships on the SBS 2011 DVDs. This tool takes into account more then a dozen additional checks that need to be done prior to a migration to ensure that the smooth migration form SBS 2003 or SBS 2008 to SBS 2011 Standard. It’s quick and easy to get the update, when you run the Migration Tool on your SBS 2003 or SBS 2008 server before you commence the migration, simply allow it to check for updates and the tool will bring the updates down and then perform the checks on your machine.
The SBS team has a blog post about the tool here
You can also find out more information about the specific checks done by the tool and the corrective actions needed here
This update is a MUST for any migration you are doing as well as reading the SBS Team blog – you can use this link to quickly check the Migration category for migration issues on SBS 2011 migrations.
