Thank you for contacting the Telerik support.
When it comes to migration from classic Telerik controls to the ones from the AJAX suite, it is recommended to contact us in separate tickets tagged with the proper product, so that we could examine carefully the provided scenario about the used control.
Tracking the information in one thread related to multiple controls will use non-productive assistance. This is why I suggest opening different tickets for each control with which a difficulty is experienced. This way our support officers will be able to isolate the problems and provide assistance on the migration matter faster and properly.
Generally, migrating of our controls should be achieved along with careful examination of the online documentation. For example, the used FormTemplate property is obsolete and the appropriate one is the ItemTemplate and further configurations should be done via the Animation properties. Please follow these materials for further information on these matters:
About the RadToolbarButton, I am unable to firmly suggest proper configuration resolution because the one should be done according to the scenario. I recommend examining this help article and configure the toolbar buttons properly according the new properties and attributes.
If you need further assistance on the controls' migration, please open new support tickets tagged with the appropriate products and provide isolated information about the control with which the difficulties are encountered.
