Re: 389 DS 2.3.6 on RHEL 9 replication between 2.3.6 and 1.3.9 389DS

[Alex Nazarenko <alexander.b.nazarenko@xxxxxxxxx>]

Thank you, Mark,

Is there a way to initialize an existing instance without rebuilding the consumer instance from scratch?

I tried this:

- remove all *db files from the consumer

- remove existing agreement from the supplier (from cn=config)

- re-run creating the agreement on the supplier with "init":

dsconf -D "***" -w *** ldap://supplier create --suffix "dc=harvard,dc=edu" --host "consumer" --port 636 --conn-protocol LDAPS --bind-dn "cn=replication manager,cn=config" --bind-passwd "***" --bind-method SIMPLE  --init consumer-RO

Still got the same error.

Thank you again,

- Alex

Hi Alex,

It definitely works, and that error means you did not "initialize" your new server/replica.  Looks like you just setup a replication agreement, but not initialize the remote replica.  Once initialized the new server will have the same database generation id and replication updates will flow.

HTH,
Mark

Hello colleagues,

 

 

We plan to move our LDAP service from 389DS 1.3.9 on RHEL7 to 389 DS 2.3.6 on RHEL 9 platform.

 

Question: is it possible to attach a 389 DS 2.3.6 consumer to 389DS 1.3.9 supplier for seamless transition, and get the data replicated in real time?

 

My first attempt produced an error about different database versions.

Maybe it is not supposed to work?

 

Thank you,

- Alex
