Well hello.
Not sure if I get the point.
You suggest the new PHP/Xoops upgrade might leave old Amiga browser users behind. There MUST be some workarounds! How about mobile plugins? Some mobile devices' profiles shouldn't go beyond Amiga browsers' demands. If there exist ones, you might simply redirect the content into a "limited" vault, which preserves all/some Aorg functionality. Also if new PHP causes old Amiga browsers to fail working, why not pass the data over some other low-end CMS providing service to the older browsers?
And what exactly do you mean by "no way to migrate data"?? It's just data, a matter of running some script transforming it to another data format, what's a big deal about it? I do not think moving xCMS data is any problematic. World is not much complicated as long as you keep data in XML, eventually with XSLT transformation.
I must be missing something, still dunno what that is.
