Estimated time to complete this lab
45 minutes
Objectives
After completing this lab, you will be able to:
Navigate through an unattached SharePoint Content Database
Export content from an unattached SharePoint Content Database
Import previously exported content
Prerequisites
Before working on this lab, you must have experience of working with previous versions of SharePoint Products and Technologies.
In addition, you should have completed Hands on Lab: Installation and Configuration of SharePoint Server 2010.
Here is another development VHD that contains the following products:
Microsoft Download Center
- Windows Server 2008 SP2 Standard Edition x64, running as an Active Directory Domain Controller for the “CONTOSO.COM” domain with DNS and WINS
- Microsoft SQL Server 2008 SP1 + CU2 Enterprise Edition with Analysis, Notification, and Reporting Services
- Microsoft Office Communication Server 2007 R2
- Visual Studio 2010 Beta 2 Ultimate Edition
- Microsoft SharePoint Server 2010 Enterprise Edition Beta 2
- Microsoft Office Web Applications Beta 2
- FAST Search for SharePoint 2010 Beta 2
- Microsoft Project Server 2010 Beta 2
- Microsoft Office 2010 Beta 2
- Microsoft Office Communicator 2007 R2
Keep in mind that many of the software included on the VHD require activation after 30 days.
MSDN, TechNet, or Partner Action Pack license keys will active software that is not Beta.
If you wish to activate Beta software check the Microsoft.com sites for each respective product and retrieve the key there.
Below is a link to a publicly available SharePoint Server 2010 VHD.
Be mindful of the system requirements, this is a resource intensive pair of VHDs.
The SharePoint VHD is set for 5Gb of memory as a default.
The Exchange is set for only 2Gb of RAM, but if you are running on a laptop you may be out of RAM by the time you spin up the SharePoint one.
I personally run a mini lab on a Dell M6400. Plenty of room and RAM 
These VHDs are also optimized for Hyper-V, a quick import in Hyper-V Manager and you are up and going.
Ask me if you need assistance in getting these labs up and going.
The two VHD downloads include SharePoint 2010 and Exchange 2010.
This is a great pre-made lab environment for learning or demonstrations.
The VHDs are not activated and will require a key.
Technet, MSDN, or the Action Pack key will work just fine.
The SharePoint VHD includes Office 2010 Beta and Visual Studio 2008.
Also, SharePoint Designer 2010 and SharePoint Workspace 2010 (updated Microsoft Groove).
