Permission-wise I can do both of it, I'm just vaguely wondering if there's anything involved I'm not aware of that could break.

For unknown reasons https://gitlab.wikimedia.org/toolforge-repos/povoconta/-/commits/master exists

@Ederporto used https://toolsadmin.wikimedia.org to create a Diffusion repository on 2022-09-07. That Diffusion repo was then migrated to https://gitlab.wikimedia.org as part of T315706: Migrate existing Striker created Diffusion repos to GitLab.

It will break rendering of https://toolsadmin.wikimedia.org/tools/id/povoconta/repos/id/673 which is linked from https://toolsadmin.wikimedia.org/tools/id/povoconta. That can be fixed by manually deleting the tools_gitlabrepo row shown in T348325#9436799. Today Striker does not have a delete function for either GitHub repos or Phabricator projects it has created to make cleaning up after this sort of change of mind by tool maintainers easier.
