Ah. I started using LMDB from scratch, so I have no first hand
experience. However, I imagine that the process is essentially:
# su -m ldap -c slapcat -n 1 > data.ldif
{ repeat for as many databases as you have...}
# service slapd stop
# pkg upgrade -f openldap-server
# vi /usr/local/etc/openldap/slapd.conf
# su -m ldap -m slapadd -n 1 -l data.ldif
{ repeat for as many databases as you have...}
# service slapd start
That's assuming you're using the old style slapd.conf file rather than a
cn=3Dconfig database. In which case you need to 'slapcat -n 1 >
config.ldif' at the beginning, modify that to change the backend DB
type, then empty out /usr/local/etc/openldap/conf/ and 'slapadd -n 0 -l
config.ldif' before loading any of the other databases.
About the only other way I can think of dong the switchover is to set up
replication to a new slapd instance using LMDB. Which has the advantage
that you could probably manage the switchover without any significant
outages.
Cheers,
Matthew
