+### Visibility rules
+
+After migration:
+
+- Private groups and projects stay private.
+- Public groups and projects:
+  - Stay public when imported into a public group.
+  - Become private when imported into a private group.
+
+If used a private network on your source instance to hide content from the general public,
+make sure to have a similar setup on the destination instance, or to import into a private group.
