The only issues I'm aware of are:

1. if you are switching to "namei" fileservers, you'll need to dump  
and reload all your volumes.  (You would have to build OpenAFS from  
source to do this; the Solaris build defaults to "inode", which is  

2. Unless built with --enable-transarc-paths (IIRC), the client and  
server configuration file locations have changed.  Very roughly (i.e.  
don't bet your cell on this without checking docs), /usr/afs is /usr/ 
local/etc/openafs/server and /usr/vice/etc is /usr/local/etc/afs.
