Hi @Sachindu-Nethmin ,

Could you please verify this?

Regarding the task to update the old Docker registry link (https://docker.wso2.com/) to the new Harbor registry (https://registry.wso2.com/harbor/projects):

I have searched through the SI (Streaming Integrator) and ICP (Integration Control Plane) documentation but was unable to find any instances of the old https://docker.wso2.com/ link.

However, I did identify the link in the EI (Enterprise Integrator) documentation and have submitted a PR to fix it:

PR Link: wso2/docs-ei#3033

Please let me know if there are any other areas I should investigate.
