+:::tip
+For safety, XO will not synchronize your pools if it detects a Netbox version that is not supported. If you wish to change that behavior, edit you `xo-server` configuration like so:

+```toml
+[netbox]
+checkNetboxVersion = false
+```
+
+Please be aware that by doing this, a Netbox update might make XO delete some of your data in Netbox.
