Re: Migrate PhpBB Plus To Icy Phoenix ???
-----------------------------------
[quote user="Vortex" post="14490"]I think first of all you have to downgrade from phpBB Plus to plain phpBB, then follow the normal upgrade procedure from phpBB to Icy ;)[/quote]

you will lose data for feautures that icy and phpbb plus support that plain phpbb doesn't, but there is nothing you can do about that.
