I'm looking to migrate a site from JFusion to p8pbb and before buying just want to check about minimum requirements for p8pbb to work.

The site is currently on Joomla 3.4.8 / phpbb3.1

I understand from your documentation on requirements that the current version of p8pbb supports phpbb3.1, but it specifies Joomla 2.5.28 or 3.6.5+

Will p8pbb work with Joomla 3.4.8 in the short term (i.e. can I put the migration from JFusion to p8pbb ahead of my step to upgrade Joomla to 3.6.5 in my website upgrade plan)?

We can't guarantee that it will work on Joomla 3.4 correctly and it's better to update to Joomla 3.6.5 first.

Besides Joomla 3.4 is too old, not supported and contains known security issues.

Yes, thanks, I realise 3.4 is out of date, hence my need to migrate various pieces of software to versions compatible with 3.6. However you are stating that it works on 2.5.28 which is even older! I shall try it out on a test environment. If your download area includes the version that was current a year ago then that would give me a nice smooth upgrade path.

Joomla 2.5 support will be dropped in new version, we don't provide outdated bridge version.

It's easy to update Joomla 3.4 to Joomla 3.6, we can help if you have simple site without tons of 3rd-party extensions.
