Peter this was explained above. You need an install not upgrade because you would be switching integrations.
I am merely trying to explain what the costs would be. You can always do the work yourself and save yourself the money. Just for a cost comparison though vbulletin charges $150.00 to install there product. I do not think our $70.00 charge is unfair so why the confusion here?
No one is going to do your import for free unless of course you do it yourself. The charge for this would depend on the time involved as in how much it would take for someone to input all the correct variables and run through the import steps it still requires human interaction here. Our custom fees are time involved.
This is all up to you if you choose to do your forum install and import to vb
yourself then you can do that. You can then come back to us and do the members renewal and reinstall.
I need to see your forum size for the import but I would guess the charge for an import would either be a half hour or an hour which would be $35.00 or $70.00
