Custom actions migration from SP 2007 to 2010

I have custom action defined in my SharePoint 2007 feature. It adds new item to document library menu.

<CustomAction Id="UserInterfaceLightUp.MobiusDiscretionaryArchivingLibMenu"
    RegistrationType="List"
    RegistrationId="101"
    GroupId="ActionsMenu"
    Location="Microsoft.SharePoint.StandardMenu"
    Sequence="1002"
ImageUrl = "/_layouts/IMAGES/MyImage.gif"
Title="My Title"/>

When I deploy it to SP 2010 I get the same behavior for 2007 UI mode and these actions becomes available fr开发者_Python百科om "Custom Commands" in 2010 UI mode. Is there any way to not allow menu appear in "Custom Commands". For this I would like to create ribbon buttons for 2010 UI mode only and menus for 2007 UI mode only.

Thanks beforehand.

Have a look at our series about porting a SharePoint 2007 solution to 2010 while maintaining compatibility with both.

In summary, to solve your problem we maintain a separate SPHive_2010 folder that contains files that will be used to overwrite the SP2007 specific ones during the build process. We build 2 separate WSP files.
