Hello @Dharani Dharan D 

Welcome to the Atlassian community.

If you want to transfer data from one Jira  Cloud instance/site to another Jira Cloud instance/site you don't use JCMA. Follow the guidance here:

Hello and welcome @Dharani Dharan D 

If your migration is Jira Cloud to Jira Cloud, you do not install the Jira Cloud Migration Assistant.

That assistant is for Server / Data Center to Cloud only.

For Cloud to Cloud, you should look at Atlassian’s data transfer / copy Jira data process instead:
