After upgrade cleanup

[Carol Walter <walterc@xxxxxxxxxxx>]

Greetings, one and all,

I just did an upgrade from 8.1 to 8.2.3.  We'll go up to 8.3.3 very  
soon, but for reasons I won't go into, this intermediate step was  
necessary.  My problem is, now that the upgrade is done, how can I  
clean up the database from the old version.  I leave the original  
database up as long as I can when I do an upgrade just in case I need  
to revert to it.  Now I have the databases from two versions on my  
server and I need to get rid of the old one.  Can I just remove the  
old files from the data directories?  With other systems, I've had  
trouble removing database files because upgrades use certain files  
from old versions.  I don't want to break my new database.  I'm on  
Solaris 10.

Thanks,

Carol
