Gitea In-House migration between organizations


In my gitea instance, i have two organizations.
Im currently playing with the thought of migrating our main repository, to the other organization.

As its an “inhouse” migration and the migration window tells that i can keep issues, pull requests and so on, i want to ask, what the possible loss would be?

I guess i have to reassign all my issues and prs.

Is there anything else that could be named a risk with that process?
Is the original repo modified during migration so in case of any failure i have the original repository left?

Thanks guys!
