direct migration form 2.11.10 -> 3.2 is not possible. you need to follow some break upgrades in b/w.

please check check release notes  https://www.gerritcodereview.com/3.2.html (Schema Changes)

Hi Brahmu,

You could start with creating local test environment:
https://gerrit.googlesource.com/plugins/multi-site/+/refs/heads/stable-3.2/setup_local_env/

This will give general idea which plugins and components are needed.

Both linux and mac platforms are supported

Best regards,
Marcin

I have setup multi site gerrit on AWS recently. I have 2 gerrit instances, kafka and zookeeper for multi-site setup.

Following plugins were needed in my case:

- websession-broker

- zookeeper-refdb

- kafka-events

- replication ( this does not work on gerrit SSH port which is usually 29418)

       - SSH key needs to be generated on both instances " ssh-keygen -m PEM -t rsa"  ( This is mandatory for replication plugin to work)

       - add instance 1's generated key to instance 2 (at ~/.ssh/authorized_keys)

       - add instance 2's generated key to instance 1

- you would also need to copy events-broker jar to $gerrit_home/lib folder (https://repo1.maven.org/maven2/com/gerritforge/events-broker/)

In terms of configuration:

$ gerrit.config

[gerrit]

         serverId = ( this has to be the same for instance1 & instance2)

         ......

[plugin "kafka-evnets"]

         ....

        groupId =  ( this would be specific to instance it can be instance-1 / instance-2)

I also copied all of the mentioned plugins to both lib and plugins folder.

Does your multi-site instance Gerrit works?

Actually, I also need a guide to tell me how to install a multi-site Gerrit step by step, unfortunately, I did not find any documents or article that told me how to.

The multi-site plugin has a test environment that you can create locally and has all the components needed (see [1]).

The multi-site plugin contains also:

- Overall installation guide (see [2]).

- Design document (see [3]).

- Configuration guide (see [4]).

NOTE: Setting up a Gerrit in a multi-site configuration isn’t trivial as it requires several skills, like configuring a Kafka PubSub broker and Zookeeper. If you would need help in getting all the components installed and up-and-running, there are companies offering consultancy and enterprise support (see [5]).
