Migration configuration from XG 18.0.5 18.0.5 MR-5-Build586 to XGS 18.5 EAP1-Build236

We have received our new XGS 126.

And we would like to migrate the configuration from our XG 125 Rev.3

Unfortunately it is not possible to upload the backup from the XG 125 to the XGS 126 because the new one comes with 18.5.0 and for the old one there is no 18.5.0 available yet.

Any idea how to avoid reconfiguring everything from scratch on the new one?

And no... it is not possible to downgrade the XGS 126 to 18.0.5 :-)
