First, sorry for my English.

I'm testing samba4 rc5. I have compiled and installed samba4 and now I'm 
trying to simulate an upgrade from my samba3 site to my samba4 test 
installation. I have setup a isolated network and I have replicated 
server and clients, copied my samba3 ldap contents and tdb files.

But, when I run samba-tool classicupgrade following to the docs, 
samba-tool complaints about wins error.

Below is the error. When the error appeared, I manually deleted the name 
entries in the wins.dat file, but the error continues with other machine 

Can I delete the wins.dat (entirely or its content) without consecuences?

I have re-run the samba-tool classicupgrade after every error. Need I to 
wipe the internal samba4 database before re-run samba-tool 
classicupgrade? If, "yes", how?
