DW converting to Wappler

I would like to switch completely to Wappler but what should be done with my dozens of sites developed in DW with its extensions.

What is the procedure? I have already done some experiments and I think a lot of work needs to be done again. Not to mention the cleaning up of unnecessary libraries and code created by DW.
It would be handy if we had a manual for converting DW websites to Wappler websites.
