Migrating Lookup Selector from SharePoint 2007 to SharePoint 2010

Be sure you have at least the Minimum SharePoint 2007 Product Release (shown in the table below) installed before migrating. If not, upgrade your Bamboo product release before migrating. For more information, see Upgrading your Bamboo Web Part. Also, the target SharePoint 2010 farm requires at least the Minimum SharePoint 2010 product release shown.

Icon-Warning IMPORTANT: When migrating from SharePoint 2007 to SharePoint 2010, you MUST select the option to change existing SharePoint sites to use the new user experience. Your Bamboo products will not perform as expected with the old look and feel.

In-Place Upgrade
Issues The Lookup Selector Column Web Part migrates without any errors or additional steps required.
Resolution N/A
Database Attach Upgrade Method
Issues The successful migration of the Lookup Selector Column when using Database Attach Upgrade depends on the original configuration of the custom column:

  1. If the custom column was configured using a relative path, then then migration will be successful without additional steps.
  2. If the custom column was configured using an absolute path, the custom column settings will display the following message in SharePoint 2010: 
The Web application at [Site URL] could not be found. Verify
that you have typed the URL correctly. If the URL should be
serving existing content, the system administrator may need
to add a new request URL mapping to the intended application.
Resolution There is currently no resolution if the Lookup Selector Column was created with an absolute path. It will need to be recreated. If the URL is updated to the correct SharePoint 2010 URL in the Lookup Selector Column settings, the settings will display the following error message:

To show the source list you should choose the correct based
URL. The user must delete this column and create a new Lookup
Selector.
