+    Too big version jumps can break the NetBox migration path. It's good
+    practise to don't skip major versions and common that you must upgrade to
+    the latest minor inside the current major version till you can upgrade to
+    the next major version. Diffrent version steps must be done manually as
+    this type only upgrades to the given version directly.
