Hello,
I am currently running 3.2.2 with mostly custom modules. I was wondering how upgrading to 3.3.5 will affect my stuff.

My primary concern are, as I think of them;

Passwords.
The previous min length on passwords is 4, will current passwords be broken?
Is this a setting somewhere so I can return it to 4? (without hacking DNN code)

Registration.
I have my own custom Registration/User info page.
Currently this fills in only a couple spots in the UserInfo object (First/Last/User Name & Email). Will I need to re-write this to fill in any additional information that is required for 3.3.5.
I can easily re-write this if needed, just want to know ahead of time.

I haven't had an opportunity to play with 3.3.5 beyond seeing some significant visual differences in the user admin section and deciding that I didn't want to try and upgrade to that right now, until I found out more info.

Any advice or encountered complications, or things I should even be concerned with about making this trasistion, please post. I will be testing it on a test site first, but a test site is never really a live site.

On a slightly related note, is it possible to back up the users, wipe everything, resinstall a fresh DNN (such as 3.3.5 instead of upgrading) and then re-load the users?

Thank you very much for any input.
