Backup and Restore. Migration from RT-AC68U to RT-AX88U Pro

[Igor]

Hello!

I am upgrading my RT-AC68U router to RT-AX88U Pro. Merlin 388.2.2. Saved settings on RT-AC68U and restored on RT-AX88U Pro.
Lost:
1. Login and password for Internet access.
2. Routing for the OpenVPN (Allowed Clients -> Common Name(CN), Subnet, Mask).
3. MAC filter list.
4. Manually Assigned IP around the DHCP list.

Can I transfer MAC addresses and DHCP settings from RT-AC68U to RT-AX88U Pro?
Do I need to clean anything after this restore?

You may have bricked your new router. Do a hard factory reset and then manually configure your new router. Do not use another config file!

Do not use another config file!

Now everything works.
How to quickly migrate OpenVPN server settings?

 

[Tech9]

I wouldn't attempt migrating settings between AC68U and AX88U Pro. They are four generations different hardware routers. Reset the new AX88U Pro and configure manually with copy/paste settings from screenshots. Otherwise "everything works" is not guaranteed in a long run.

 

[Igor]

I understand that you need to do a reset. Is it possible to export some settings? For example:

From RT-AC68U

# nvram get dhcp_staticlist
# nvram get wl_maclist
# nvram get wl0_maclist
# nvram get wl0_maclist_x
# nvram get custom_clientlist
# nvram get sshd_authkeys
# nvram get vpn_server_ccd_val
# nvram get vpn_server_ncp_ciphers
...

To RT-AX88U_PRO

# nvram kset ...

If yes, what is the syntax of kset?

# nvram kset filter_lwlist=<>445>>>TCP ...

- error

What do I need to export for an OpenVPN server?

 

[ColinTaylor]

The correct command is "set" not "kset", and you need double quotes around the contents, e.g.

# nvram get filter_lwlist
<>>>445>TCP
# nvram set filter_lwlist="<>>>445>TCP"

The OpenVPN server settings are spread across numerous nvram variables as well as files in /jffs/openvpn.

I would make a screenshot of settings and export the certificate only. On the new router configure the server as before and import the certificate.
