There are no longer "upgrade" and "full install" separation; the only difference in the "full install files with UBB.C where the variables files not being included.

In order to "migrate" from UBB.C to UBB.T7 you must upgrade to a version of UBB.C 6.7.x (any version within it really).

Do you need Forum Install or Upgrade Services?
