apache13 to apache13-modssl port migration

[culley harrelson]

I am currently running /usr/ports/www/apache13 and I want to switch to 
/usr/ports/www/apache13-modssl.  Has anyone make this transition?  I 
don't know what to expect and I don't have a freebsd test box right now. 
  I am worried about the ports dependent on apache13-- what happens to 
them if I just install apache13-modssl on top?  I do use portupgrade.
