I'm not sure this is the correct place to ask but here goes nothing.
Mid 2008, I installed punbb 1.3 forum software. It was iirc a 300kb upload and I needed a forums running in minutes. I didn't know mybb or phpbb existed. Plus I was new to the webmaster world. Little did I know back then that this is a dead project (currently running 1.3.4). It was forked into fluxbb but fluxbb is based on punbb 1.2 and also fluxx is missing a captcha extension.

My question is: Is there any forum software that I can convert to from punbb 1.3 and not lose data?
