How to Migrate a Bamboo Web Part from SharePoint 2007 to SharePoint 2010 using the Database Attach Upgrade Method

When you upgrade by using database attach upgrade, you detach the databases in the old farm and then attach them to the new farm. When you attach a database to the new farm, the SharePoint upgrade process runs and upgrades the whole database. The database attach upgrade process is similar to the in-place upgrade process. The difference is that the database attach upgrade process is performed manually, and is performed in a separate environment.

Using the Database Attach Upgrade method, the following products migrate to SP2010 with no errors or additional steps:

Chart Plus
Cross List
Column Level Security
Custom Identifier Column
Data-Viewer
Group Email
Group Redirect

List Search Simple
List Search Advanced
Mini-Calendar
Site Creation Plus
Task Master
Tree View
User Manager for Sites

Password Expiration
User Redirect
Validator Column
Visual Indicator Column
Wiki Publisher
World Clock and Weather

NOTE: If you are using a Bamboo product that is not on the above list and you are considering using the Database Attach Upgrade method to migrate your farm, refer to the specific migration information for your product to learn more about possible limitations before proceeding with a migration.

Step	Action
1.	The first step in the process is to set up a new environment to host the upgraded content. See Prepare the new SharePoint Server 2010 environment for a database attach upgrade for additional information from Microsoft.
2.	After you set up the new environment, use the procedures in Microsoft’s Attach Databases and Upgrade to SharePoint 2010 article to detach and then reconnect the databases to perform the actual upgrade. NOTE: When attaching the databases, you must choose to update to the new user experience. Your Bamboo products will not perform correctly if you choose to remain in the old user experience after upgrade.
3.	During the upgrade process or before, retrieve the installation package and license keys for the SharePoint 2010 release of the Bamboo product(s) you are migrating. See Migrate My Existing Bamboo Product License Key From SharePoint 2007 to SharePoint 2010 for additional details.
4.	After successfully upgrading to SharePoint 2010 and after all databases have been attached and converted, run the SharePoint 2010 Bamboo product installation package that you retrieved in Step 3. Since this will be a new install on new hardware, you will be asked to choose the Web Applications to deploy to. Be sure to select the same Web Applications where the Bamboo product was deployed on the old farm. For more information about installation, refer to How to run the Installation-Setup Program.
5.	Install the Bamboo Web License Manager provided in the same installation package. NOTE: The Bamboo Web License Manager only has to be installed once. Skip this step for subsequent Bamboo product installations.
6.	Activate the SharePoint 2010 versions of Bamboo products. See Activating Your Bamboo Product License for more information.
7.	Refer to specific migration steps for the Bamboo product(s) you are migrating. There may be some extra steps required to overcome a known migration issue.
