Importing OpenVPN Access Server profile to OpenWrt

Hello,
I have a remote GSM router running OpenWrt, which is connecting to the Access Server as a client. The connection works fine, untill the certificate expires or gets corrupted. I would like to ask, whether there is a way to import profile from Access Server to the OpenWrt (or any other) linux device, like it is possible on windows with OpenVPN GUI.
