+# Migrate calendars from La Suite Calendars (CalDAV) to Stalwart (CalDAV).
+#
+# Exports all calendars per user from the old CalDAV endpoint and imports them
+# into Stalwart's CalDAV endpoint.
+#
+# Prerequisites:
+#   - curl
+#   - Port-forward to both old calendars-backend and new Stalwart:
+#       kubectl port-forward -n lasuite svc/calendars-backend 8081:80 &
+#       kubectl port-forward -n stalwart svc/stalwart 8080:8080 &
+#
+# Usage:
+#   ./migrate-calendars.sh \
+#     --old-url http://127.0.0.1:8081 \
+#     --new-url http://127.0.0.1:8080 \
+#     --new-user admin --new-password <pw> \
+#     --users "sienna@sunbeam.pt,amber@sunbeam.pt,lonni@sunbeam.pt"
