I upgraded the forum from UBB Classic to UBB.threads last year. The new forum resides in a separate directory:
Code
domain/forums

Question:
Are there any shared files between UBB Classic and UBB.threads in the CGI-Bin?

I am looking to delete the directories for the old board:
Code
domain/ubb
and
Code
domain/cgi-bin/ubbcgi

Is it safe to do so without affecting the UBB.threads board? I know that the two boards are completely different software (perl flat files vs. database) and reside in different directories... I just want to make sure that there isn't a renegade script, license or other file that is shared between the two before I delete the old board.
