Bottom Paint - Transitioning from Saltwater to Fresh Water

[S/V Illusion]

This will be our first cruise into the Great Lakes and it got me thinking what I will need to do to transition from the ablative paint currently on her bottom.

I know the theory and have read the mfg's directions but for those who have actually done it, do I really need to remove all the ablative and substrate copolymer or will the VC17 adhere to the existing hard paint?

Why transition? We used Micron CSC for yrs on the Great Lakes then we went went the the Chesapeake kept on using it. I would doubt you need to make a change at all, especially on a cruising boat. VC17 is a race paint.
