Dear Vivek,
Currently it’s not possible to migrate a Portfolio plan directly from Jira Server to Jira Cloud.
However, if you follow the steps at Exporting a Report (scope) to CSV, and then re-build your plan from that scope, that is a helpful step that gets you part of the way. The article Configuring the Scope table can also help you better understand what is part of the scope table.
