Thank you for contacting Telerik Support.
Since you are using Q3 2010 where all obsolete controls exists and their descendants exist too you can use the Conversion tool to upgrade most of the obsolete controls. Here are some links demonstrating how to achieve this:
- RadTabStrip to RadPageView
- RadPanelBar to RadPageView
- RadComboBox to RadDropDownList
- RadListBox to RadListControl
Additionally, If you have used the old implementation of our docking control (DockingManger), you will be able to convert it to the new implementation (RadDock), again from an option in the old control Smart Tag.
The only obsolete control which you will manually convert is the RadToolStrip control. The reason for not providing a tool for conversion of this control is the fact that both controls are semantically different, so you will have to manually recreate the control by using RadCommandBar. From my experience, I can say that this is an easy conversion.
After you convert all your controls to their descendants and clean all errors and warnings, then you can perform an upgrade to Q3 2011 SP1.
I hope that you find this information helpful. If you have any questions, during the transition process, do not hesitate to contact us.
