1) For example, does the built-in importer import vb4 albums? Will the XF Media Gallery import vbgallery attachments and redirect the old links/pages? Is it possible for the built-in importer to convert blogs and groups into threads?
2) This 3rd party importer https://xenforo.com/community/resources/vb4-importer.1025/ says that it can import blogs albums and threads. However, it's quite old and I don't know if there are things the new built in importer can do that are better, or if xf 1.4.5 breaks that importer.. Will it still work?
3) This expensive 3rd party importer https://xenforo.com/community/resou...importer-vbulletin-3-vbulletin-4.1981/reviews says it's very fast but I see no mention or sign that it deals with groups or blogs. However, it seems to include things that the others may not (like daily stats, reported posts, etc).
4) There's ARFI https://marketplace.digitalpoint.com/a-r-f-i-a-really-fast-vb4-importer.908/item that #3 is based on. Not sure how much was changed from ARFI but it would basically be free for me. I know PHP and shell but don't want to waste dozens of hours.
So the dilemma is that you can't use more than one importer, and every one appears to leave out things that the others don't. Any advice here? I requested a quote from a member on doing this for several forums, but I was told not to expect the groups and blogs to transfer (this isn't super important but would be nice).
