So, I've been 'attempting' to get a converter to work from vBulletin 4.2.5 to 3.2.5 for a lot of days now. I even attempted:
To install from a phpBB 3.0.11 installation, with semi success. It appears that forums, threads, etc are being properly imported. But most posts text are completely empty.
I've even attempted to install it under PHP 5.6, but I keep getting "signal Segmentation fault" crashes after a while when the converter ran. Regardless if I increased the timeout, memory, etc. It was almost instant at a specific convert content. Upgrading to PHP 7.0/7.1 or 7.2 leads to a lot PHP warnings/errors, but is to be expected how old the converter is but oddly enough it did finish the convert but leads to empty/blank posts as per image above.
I've also been looking for hours and noticed that there is no other converters out there, which is quite a shame. I know there are people who are be willing to be paid for it, but I actually wanted to test phpbb first with my own imported board to its full extend but that's almost impossible seeing the state of the ancient and or non-existing importers.
So, if there are no other converters out there (someone really should be making one) is it maybe possible to use a middleman instead? For example:
vB4 -> XenForo -> PHPBB 3.2.x
vB4 -> SMF -> PHPBB 3.2.x
Using Xenforo or SMF as a convert middleman to phpbb. Yes, I should this would mean you are converting twice. But if the end results are good, why not?
