Upgrading from nightly?

[genesisrage]

id assume proftpd is started correctly, but apparently not, because it still doesnt work.

when in debug (9) and i try to connect i get this

Code:

genesisrage.vps - ROOT PRIVS at main.c:1185
genesisrage.vps - RELINQUISH PRIVS at main.c:1189

and the error i get on the client is this

Code:

421 Service not available, remote server has closed connection

i checked my proftpd.conf file and found that line, however i was not able to connect... infact the 'ispcp' user didnt even exist, so i created the user with the same password and was able to connect (to mysql).

when reloading everything and trying again, i still get the same errors above. so i have no clue on what is going on. so i guess im back at my original question, how exactly can you upgrade from a nightly to an RC without loosing web and mail data?
