Description thierry bordaz 2022-09-13 16:00:12 UTC

Document URL: https://access.redhat.com/documentation/en-us/red_hat_directory_server/12/html/installing_red_hat_directory_server/index

Section Number and Name: 
Upgrade of a MMR topology

Describe the issue: 
I have not seen any documentation explaining how to upgrade a full MMR topology

Suggestions for improvement: 

Suggested steps
For the first instance,

remove replication agreement from/to the instance
export all backends (with replication)
remove instance
upgrade RPM
create instance
configure instance
import backends
recreate RA from/to instance

For the next instances, make sure all direct updates have been replicated on the first instance

remove RA from/to
remove instance
upgrade RPM
create/configure instance
import backends from the first instance export
recreate RA from/to
Prevent direct update on that host until it is fully in sync

Hi Thierry,

Comment 2 Pierre Rogier 2022-09-13 18:08:46 UTC

A comment: 
  - This procedure should only be used when upgrading from a major version to another one 
    (For minor upgrade, simply upgrading each instance is OK.)
