tier 1 dependant and later changed to PBS dependant
They are the SAME visa category.
You must apply on the Tier 1 Dependent form.
If you use the form in the link you have provided, your spouses' clock towards ILR will be reset to zero and a new 5 year residence period before they will qualify for ILR.
Have you read the links that 'vinny' provided properly, which also contains links??
