[Redux]How to downgroad this to patch 5017

Hello, same in thread and sorry for my little english.
I liked a redux source but i need to downgroade it to 5017 patch, but i know only one a 5065 clients used a blowfish key, 5017 no have a blowfish... Anyone can tell me how can i downgroad this source? i don't want your work I need help to understand how the client connect to the server and server to the client. What patch i need to be changed. I know i need to change all packets about walking etc, but what i need make in first step to log in? Thanks anyone for help, regards.

Swap encryption
Swap packet structures
Swap some game systems/sequences
Re-dump all the client files to DB (may require re-structuring)
Re-design all the item ID calculations (they work differently in that client due to color value being part of the item)

Oh shit it's really too hard make it :P but thanks for your answer Cris.

Good Luck in it
