No, but it would be a piece of cake to migrate the data. OI uses 
session-based authentication with cookies rather than HTTP 
authentication.

Since OI uses standard Perl modules for many of the pieces -- 
session handling uses Apache::Session, view processing uses the 
Template Toolkit, parameter parsing (etc.) uses Apache::Request, 
etc. -- the only porting for those pieces should be simple, 
assuming that you've kept them fairly separate.

Porting your business logic (or whatever you'd like to call it) 
will be more of an effort. How much depends on the degree you've 
separated your tasks out already. So if you have a single method 
that does all create/update/delete actions for a single record, 
you will have quite a bit of work. But if you're using the same 
sort of paradigm that CGI::Application uses, it shouldn't be 
difficult at all.

As for the load: to my knowledge Andreas Nolte and his crew have 
  built the largest and most used system based on OI. If he says 
it scales well, I tend to believe him :-) What's useful is that 
all the helpful hints in the mod_perl guide are directly 
applicable, and OI comes out of the box configured to use the 
dual-server proxy setup the guide recommends.

Good luck!
