OK. I have decided to cop out. I am simply going to copy all database information from my Production Server over to my Development Server and leave well alone. I think that should work. Please let me know if that won't.

Irrelevant reasoning
Redacting the 5.3 build within WAMP on my Development Machine seems stupid. Won't do it. But MySQL surely works.
My ISP's PHP build on my Public Production Server is less than 5.3. It is their responsibility to update MySQL properly when they choose to update. If I mess around with it I risk not having support should I make an error. So best leave alone.
Connecting from 5.3 on my Development Server to MySQL within the pre-5.3 on the Production Server is broken. Can't do that.
So I'm surely better off simply copying the database of information from my Production MySQL to my Testing MySQL and simply connecting differently within each environment. Since the databases and fields will have the same names, the only difference will be in the Connection Scripts located in the two places, one connecting to localhost, the other connecting to my public domain.
Can't see why that shouldn't work.
If anyone reading this can see a flaw, please let me know.
Thanks. Bye now.
