migrate GG classic to GG Microservices in a hub configuration

cptkirksh

I want to start off to say this is all in a test environment. I have two Oracle 18c DBs. I have GG 19 Classic set up in a separate hub config that connects via the Oracle client software on the hub server. I want to learn more about Microservices. What is the best approach to convert that classic GG setup to Microservices? Thanks in advance.

As of now, we don't have a method to upgrade from Classic to Microservices. This is because, the architecture is entirely different between Classic and Microservices.

The steps would be,

1. Get a downtime. Application should be stopped. No data flow should be on the system. It is better to do in tech window (if production environment).
2. Make sure all the transactions are processed by the GG processes.
3. Stop all the GG processes in Classic GG home including Manager.
4. Create the processes in Microservices Home.
5. Start the processes.

I have written few articles in OGG Microservices which are below and might be useful to you.
