Jira C2C tool to support incremental migration

Problem definition

Currently, the Jira C2C tool does not support the migration of projects that are already present on the destination Cloud site.

Suggested Solution

It would be helpful if we could have a differential migration feature in the C2C tool.

Have a migration saved in the source system, then click a button and the tool would take the projects/issues diffs, find the corresponding in the target system, and just apply the changes.

This helps because oftentimes, users keep working in the source systems even as we do the initial migration and it would save time instead of remigrating everything again to the cloud destination.
