Import users from 4.5.9 on 5.0.5 (OS)

[FreezeS]

Hello,

I'm trying to create an empty server to be used while I reinstall and upgrade our 4.5.

I've followed the steps from here: http://www.zimbra.com/blog/archives/...ap_data_1.html

But when I try to delete the imap database I get an error that there are subfolders. If I skip this step, I'm getting this:

The first database does not allow slapadd; using the first available one (2)
=> bdb_tool_entry_put: id2entry_add failed: DB_KEYEXIST: Key/data pair already exists (-30996)
=> bdb_tool_entry_put: txn_aborted! DB_KEYEXIST: Key/data pair already exists (-30996)
slapadd: could not add entry dn="cn=zimbra" (line=12): txn_aborted! DB_KEYEXIST: Key/data pair already exists (-30996)


How can I clear the existing data ? If I delete the ldap folder this messes up everything.
