XF 1.1 Importing from phpBB3 to XenForo

I have a phpBB3 forum that I want to convert to XenForo, but I keep on getting errors on how the attachment directory and avatars directory can't be found.

The defaults for them are:
Custom Avatar Path: images/avatars/upload
Attachment Path: files

What should I do?

Thanks for the help!
Nevermind, I figured out the solution.

Needed to change to ../[phpbb3 path]/images/avatars/upload
../[phpbb3 path]/files
