f17 -> f18, fedora-upgrade, all is well but slapd

[Maurizio Marini]

I have upgraded f17 to f18 w/ fedora-upgrade and all went smoothly :)
only this issue:

# slapcat

51792415 bdb(dc=my-domain,dc=com): BDB1538 Program version 5.3 doesn't match environment version 5.2
51792415 bdb_db_open: database "dc=my-domain,dc=com" cannot be opened, err -30969. Restore from backup!
51792415 backend_startup_one (type=bdb, suffix="dc=my-domain,dc=com"): bi_db_open failed! (-30969)
slap_startup failed

I forget to do a backup before upgarding, how can I fix?
mant thnx
