Migrating Symantec Backup EXEC 2010 R3 SBS installation to another machine

Hi All,

I have Symantec Backup EXEC 2010 R3 Small Business Server running on a Windows 2008 SBS Virtual Machine.I am planning to create a new VM

with Windows 2008 SBS & install Symantec Backup EXEC 2010 R3 Small Business Server on it. 

Please help me to properly do the migration.

Also I want to know the differences between Symantec Backup EXEC 2010 Small Business Server  & Symantec Backup EXEC 2010 ??

Thanks.
