Need a "Hard Limit" documentation on size/scope supported on Migrations

Currently, we have a "Soft Limits" documentation - https://support.atlassian.com/migration/docs/soft-limits-for-cloud-to-cloud-migration-for-jira/.

I have since encountered a number of tickets where the customer was following the limits laid out in the guide but were encountering issues due to the size/scope of their migration.

Having a "Hard Limit" will greatly help our customer prepare and strategize for their migration journey and would limit the amount of tickets opened with Migrations Support.
